Question 1

Three of the following terms are alike in a certain way. Find the odd one out

Accepted Answer

Correct Option: ZCF. To identify the odd one out, we need to analyze the positional values of the letters in each term and find a consistent pattern. Step 1: Assign numerical positions to the letters for each term (A=1, B=2, ..., Z=26). Option A: NQS N = $14^{th}$ Q = $17^{th}$ S = $19^{th}$ Pattern: $14 xrightarrow{+3} 17 xrightarrow{+2} 19$ Option B: HKM H = $8^{th}$ K = $11^{th}$ M = $13^{th}$ Pattern: $8 xrightarrow{+3} 11 xrightarrow{+2} 13$ Option C: ZCF Z = $26^{th}$ C = $3^{rd}$ (or $26+3 = 29^{th}$ if wrapping around) F = $6^{th}$ (or $26+6 = 32^{th}$) Pattern: $26 xrightarrow{+3} 3$ (Z to C, Z $rightarrow$ A $rightarrow$ B $rightarrow$ C) $3 xrightarrow{+3} 6$ (C to F, C $rightarrow$ D $rightarrow$ E $rightarrow$ F) So, the pattern is $(+3, +3)$. Option D: TWY T = $20^{th}$ W = $23^{rd}$ Y = $25^{th}$ Pattern: $20 xrightarrow{+3} 23 xrightarrow{+2} 25$ Step 2: Compare the patterns. The patterns for NQS, HKM, and TWY are all $(+3, +2)$. The pattern for ZCF is $(+3, +3)$. Step 3: Identify the odd one out. ZCF has a different pattern compared to the other three. Therefore, ZCF is the odd one out.

Question 2

Which number will replace the question mark (?) in the following series ? $0.15, 0.20, 0.30, 0.45, 0.65, ?$

Accepted Answer

Correct Option: 0.9. To find the missing number in the series, we need to identify the pattern of differences between consecutive terms. Step 1: Calculate the differences between adjacent terms. Difference between $0.20$ and $0.15$: $0.20 - 0.15 = 0.05$. Difference between $0.30$ and $0.20$: $0.30 - 0.20 = 0.10$. Difference between $0.45$ and $0.30$: $0.45 - 0.30 = 0.15$. Difference between $0.65$ and $0.45$: $0.65 - 0.45 = 0.20$. Step 2: Analyze the pattern of these differences. The differences are $0.05, 0.10, 0.15, 0.20$. This is an arithmetic progression where each term increases by $0.05$. Step 3: Determine the next difference in the pattern. The next difference should be $0.20 + 0.05 = 0.25$. Step 4: Calculate the next term in the series. Add the next difference ($0.25$) to the last given term ($0.65$): $0.65 + 0.25 = 0.90$. Step 5: Evaluate the options. Option A: $0.8$. This is incorrect. Option B: $0.9$. This matches our calculated result ($0.90$). Option C: $0.85$. This is incorrect. Option D: $0.95$. This is incorrect. Therefore, the number that replaces the question mark is $0.9$.

Question 3

If V=44 and FAT=54, then MASTER = .

Accepted Answer

Correct Option: 152. To find the value of 'MASTER', we need to determine the coding rule from the given examples: V=44 and FAT=54. Step 1: Analyze the coding for 'V'. The letter V is the $22^{nd}$ letter in the alphabet. Given V = $44$. We can see that $22 times 2 = 44$. This suggests the rule might be (positional value of letter) $times 2$. Step 2: Analyze the coding for 'FAT'. F is the $6^{th}$ letter. A is the $1^{st}$ letter. T is the $20^{th}$ letter. Sum of positional values: $6 + 1 + 20 = 27$. Given FAT = $54$. We can see that $27 times 2 = 54$. This confirms the rule: (Sum of positional values of all letters) $times 2$. Step 3: Apply the rule to 'MASTER'. Assign positional values to each letter in 'MASTER': M = $13^{th}$ A = $1^{st}$ S = $19^{th}$ T = $20^{th}$ E = $5^{th}$ R = $18^{th}$ Sum of positional values: $13 + 1 + 19 + 20 + 5 + 18 = 76$. Step 4: Multiply the sum by 2. $76 times 2 = 152$. Step 5: Evaluate the options. Option A: $146$. This is incorrect. Option B: $152$. This matches our calculated result. Option C: $158$. This is incorrect. Option D: $162$. This is incorrect. Therefore, 'MASTER' = $152$.

Question 4

In a code language, DEAR is written as WVZI. How will SOUTH be written in the same language ?

Accepted Answer

Correct Option: HLFGS. To decode the word 'SOUTH', we first need to understand the coding pattern used for 'DEAR' to 'WVZI'. Step 1: Assign numerical positions to the letters of 'DEAR' and 'WVZI' (A=1, B=2, ..., Z=26). For 'DEAR': D=4, E=5, A=1, R=18. For 'WVZI': W=23, V=22, Z=26, I=9. Step 2: Analyze the relationship between corresponding letters. - D ($4$) and W ($23$): $4 + 23 = 27$. - E ($5$) and V ($22$): $5 + 22 = 27$. - A ($1$) and Z ($26$): $1 + 26 = 27$. - R ($18$) and I ($9$): $18 + 9 = 27$. The pattern is that each letter is replaced by its 'opposite' letter in the alphabet, such that the sum of their positional values is $27$. This is a standard reverse alphabet coding. Step 3: Apply the same coding pattern to 'SOUTH'. For 'SOUTH': S=19, O=15, U=21, T=20, H=8. - For S ($19$): The opposite letter will have position $27 - 19 = 8^{th}$, which is H. - For O ($15$): The opposite letter will have position $27 - 15 = 12^{th}$, which is L. - For U ($21$): The opposite letter will have position $27 - 21 = 6^{th}$, which is F. - For T ($20$): The opposite letter will have position $27 - 20 = 7^{th}$, which is G. - For H ($8$): The opposite letter will have position $27 - 8 = 19^{th}$, which is S. Combining these, 'SOUTH' is coded as 'HLFGS'. Step 4: Evaluate the options. Option A: HLFGS. This matches our derived code. Option B: SGFLH. This is incorrect. Option C: HFLGS. This is incorrect. Option D: HFLSG. This is incorrect. Therefore, the correct option is 'HLFGS'.

Question 5

Three of the following four numbers are alike in a certain way and one is different. Find the odd one out

Accepted Answer

Correct Option: 121. To find the odd one out, we need to examine the properties of each number. Step 1: Analyze each number for common mathematical properties such as divisibility, perfect squares/cubes, or sum of digits. Option A: $136$ - Not a perfect square ($11^2=121, 12^2=144$). - Not a perfect cube ($5^3=125, 6^3=216$). - Divisibility: $136 = 8 times 17$. It is a multiple of $17$. - Sum of digits: $1+3+6 = 10$. Option B: $102$ - Not a perfect square ($10^2=100, 11^2=121$). - Not a perfect cube ($4^3=64, 5^3=125$). - Divisibility: $102 = 6 times 17$. It is a multiple of $17$. - Sum of digits: $1+0+2 = 3$. Option C: $121$ - This is a perfect square: $11^2 = 121$. - Not a perfect cube. - Divisibility: $121$ is not a multiple of $17$ ($121 div 17 approx 7.11$). - Sum of digits: $1+2+1 = 4$. Option D: $153$ - Not a perfect square ($12^2=144, 13^2=169$). - Not a perfect cube ($5^3=125, 6^3=216$). - Divisibility: $153 = 9 times 17$. It is a multiple of $17$. - Sum of digits: $1+5+3 = 9$. Step 2: Identify the common property and the outlier. Numbers $136$, $102$, and $153$ are all multiples of $17$. $136 = 17 times 8$ $102 = 17 times 6$ $153 = 17 times 9$ Number $121$ is not a multiple of $17$. Instead, it is a perfect square ($11^2$). Therefore, $121$ is the odd one out.

Question 6

Study the pattern and replace the question mark (?) from the given alternatives.

Accepted Answer

Correct Option: 7. The diagram presents three rows of numbers, and we need to find the missing number in the third row. Let's denote the numbers in each row as $(C1, C2, C3)$. Row 1: $(43, 11, 6)$ Row 2: $(50, 31, 9)$ Row 3: $(42, 21, ?)$ Step 1: Analyze the relationship in Row 1. Let's try various arithmetic operations. Consider the sum of the first two numbers divided by the third number: $(C1 + C2) div C3 = (43 + 11) div 6 = 54 div 6 = 9$. Step 2: Analyze the relationship in Row 2 using the same pattern. $(C1 + C2) div C3 = (50 + 31) div 9 = 81 div 9 = 9$. Step 3: Identify the consistent pattern. Both Row 1 and Row 2 follow the pattern: $(C1 + C2) div C3 = 9$. Step 4: Apply the pattern to Row 3 to find the missing number. For Row 3: $(42, 21, ?)$ $(42 + 21) div ? = 9$ $63 div ? = 9$ To find '?', we calculate $? = 63 div 9 = 7$. Step 5: Evaluate the options. Option A: $7$. This matches our calculated result. Option B: $8$. This is incorrect. Option C: $5$. This is incorrect. Option D: $4$. This is incorrect. Therefore, the number that replaces the question mark is $7$.

Question 7

Study the pattern carefully and select the number that can replace the question mark (?)

Accepted Answer

Correct Option: 11. The diagram shows a sequence of numbers at the top vertices of three interconnected triangles: $7, 6, 9, 12, ?, 7$. The question mark represents the fifth number in this sequence. Let's denote the sequence as $N1, N2, N3, N4, N5, N6$. Step 1: Analyze the pattern in the sequence of numbers at the top vertices. $N1 = 7$ $N2 = 6$ $N3 = 9$ $N4 = 12$ $N5 = ?$ $N6 = 7$ Let's look at the differences between consecutive numbers: $N2 - N1 = 6 - 7 = -1$ $N3 - N2 = 9 - 6 = +3$ $N4 - N3 = 12 - 9 = +3$ Step 2: Identify the pattern of differences. The pattern of differences observed is $(-1, +3, +3)$. This suggests a repeating cycle of differences, or a pattern where $+3$ occurs twice after an initial $-1$. If this pattern of differences repeats, the next difference should be $-1$. Step 3: Apply the pattern to find $N5$. The last known difference was $+3$ (from $N3$ to $N4$). Following the sequence of differences $(-1, +3, +3)$, the next difference should be $-1$. So, $N5 = N4 + (-1) = 12 - 1 = 11$. Step 4: Verify the pattern with $N6$ (optional, as the question asks for $N5$). If $N5 = 11$, then the next difference in the pattern should be $+3$. $N6 = N5 + 3 = 11 + 3 = 14$. However, the given $N6$ is $7$. This indicates that the pattern of differences might not be strictly repeating for the entire sequence, or the last number '7' is an anomaly or part of a different sub-pattern not affecting the question mark's position. Given the options, $11$ is a strong candidate based on the established sequence of differences up to the question mark. Step 5: Evaluate the options. Option A: $15$. This would imply a $+3$ difference ($12+3=15$), breaking the $(-1, +3, +3, -1)$ sequence. Option B: $14$. This is incorrect. Option C: $13$. This is incorrect. Option D: $11$. This matches our derived result based on the repeating difference pattern. Note: The numbers at the bottom of the triangles ($169 = 13^2$, $441 = 21^2$, $324 = 18^2$) represent the squares of some combinati

Question 8

A+B means A is sister of B A-B means A is daughter of B A$times$B means A is brother of B A$div$B means A is husband of B If V+U$times$Q-T$div$R+P$times$S then how is P related to V ?

Accepted Answer

Correct Option: Maternal uncle/ मामा. We need to decode the given expression $V+Utimes Q-Tdiv R+Ptimes S$ step-by-step to build the family tree and determine the relationship between P and V. Step 1: Decode each part of the expression. 1. $V+U$: 'A+B means A is sister of B'. So, V is the sister of U. (V is female, U's gender is unknown yet). 2. $Utimes Q$: 'A$times$B means A is brother of B'. So, U is the brother of Q. (U is male, Q's gender is unknown yet). From (1) and (2), V is sister of U, and U is brother of Q. This means V, U, and Q are siblings. V is female, U is male. 3. $Q-T$: 'A-B means A is daughter of B'. So, Q is the daughter of T. (Q is female, T's gender is unknown yet). Since Q is the daughter of T, and V, U, Q are siblings, T is the parent of V, U, and Q. 4. $Tdiv R$: 'A$div$B means A is husband of B'. So, T is the husband of R. (T is male, R is female). From (3) and (4), T is the father and R is the mother of V, U, and Q. 5. $R+P$: 'A+B means A is sister of B'. So, R is the sister of P. (R is female, P's gender is unknown yet). 6. $Ptimes S$: 'A$times$B means A is brother of B'. So, P is the brother of S. (P is male, S's gender is unknown yet). Step 2: Construct the family tree based on the decoded relationships. - T (+) is married to R (-). - T and R are the parents of V (-), U (+), and Q (-). - R (-) is the sister of P (+). - P (+) is the brother of S. Family Structure: T(+) = R(-) | | V(-), U(+), Q(-) | P(+) -- S (R and P are siblings) Step 3: Determine how P is related to V. V's mother is R. P is the brother of R. Therefore, P is V's mother's brother. Mother's brother is known as Maternal Uncle (मामा). Step 4: Evaluate the options. Option A: Paternal uncle/ चाचा. This would be father's brother. Incorrect. Option B: Paternal aunt/ चाची. This would be father's sister or paternal uncle's wife. Incorrect. Option C: Maternal uncle/ मामा. This matches our derived relationship. Option D: Maternal aunt/ मामी. This would be mother's sister or maternal u

Question 9

In the following diagram, the triangle represents engineers, the circle represents sportsmen and the rectangle represents artists. The numbers in different segments show the number of persons. How many engineers are there who are neither sportsman nor artist ?

Accepted Answer

Correct Option: 4. To answer the question, we need to identify the region in the Venn diagram that represents 'Engineers who are neither sportsman nor artist'. Step 1: Understand the representations: - Triangle represents Engineers. - Circle represents Sportsmen. - Rectangle represents Artists. Step 2: Identify the target region. The question asks for the number of engineers who are neither sportsmen nor artists. This means we are looking for the number(s) that are exclusively within the triangle and do not overlap with the circle or the rectangle. Step 3: Examine the diagram for the specified region. - The number '23' is located solely within the triangle, outside of both the circle and the rectangle. This region represents engineers who are neither sportsmen nor artists. Step 4: Compare the result with the given options. The number of engineers who are neither sportsmen nor artists is $23$. However, the provided options are: Option A: $4$ Option B: $6$ Option C: $8$ Option D: $7$ None of the options match the correct answer of $23$ based on the literal interpretation of the question and the diagram. This indicates a discrepancy in the question or the options provided in the source document. Step 5: Analyze why the given options are incorrect for the stated question: - Option A ($4$): Represents engineers who are also sportsmen AND artists (intersection of all three figures). - Option B ($6$): Represents engineers who are also sportsmen but NOT artists (intersection of triangle and circle, outside rectangle). - Option C ($8$): Represents engineers who are also sportsmen AND artists (another part of the intersection of all three figures). - Option D ($7$): Represents engineers who are also sportsmen but NOT artists (another part of the intersection of triangle and circle, outside rectangle). Since the literal answer (23) is not an option, and to fulfill the requirement of providing a correctoptionindex, we acknowledge that the question as stated is flawed with respe

Question 10

Select the letter cluster that will replace the question mark (?) in the following series : EQM, GRL, ISK, ?, MUI

Accepted Answer

Correct Option: KTJ. To find the missing letter cluster, we need to analyze the pattern of transformation for each letter position across the series. Step 1: Analyze the first letter of each cluster. E ($5^{th}$) $rightarrow$ G ($7^{th}$) $rightarrow$ I ($9^{th}$) $rightarrow$ ? $rightarrow$ M ($13^{th}$) The pattern is an increase of $2$ for each step: $5+2=7$, $7+2=9$. Following this pattern, the next first letter will be I ($9$) $+ 2 = 11^{th}$ letter, which is K. To verify, K ($11$) $+ 2 = 13^{th}$ letter, which is M. This confirms the pattern for the first letter. Step 2: Analyze the second letter of each cluster. Q ($17^{th}$) $rightarrow$ R ($18^{th}$) $rightarrow$ S ($19^{th}$) $rightarrow$ ? $rightarrow$ U ($21^{st}$) The pattern is an increase of $1$ for each step: $17+1=18$, $18+1=19$. Following this pattern, the next second letter will be S ($19$) $+ 1 = 20^{th}$ letter, which is T. To verify, T ($20$) $+ 1 = 21^{st}$ letter, which is U. This confirms the pattern for the second letter. Step 3: Analyze the third letter of each cluster. M ($13^{th}$) $rightarrow$ L ($12^{th}$) $rightarrow$ K ($11^{th}$) $rightarrow$ ? $rightarrow$ I ($9^{th}$) The pattern is a decrease of $1$ for each step: $13-1=12$, $12-1=11$. Following this pattern, the next third letter will be K ($11$) $- 1 = 10^{th}$ letter, which is J. To verify, J ($10$) $- 1 = 9^{th}$ letter, which is I. This confirms the pattern for the third letter. Step 4: Combine the determined letters. The missing letter cluster is K T J. Step 5: Evaluate the options. Option A: JTK. Incorrect. Option B: KTJ. This matches our derived cluster. Option C: JVK. Incorrect. Option D: KVJ. Incorrect. Therefore, the correct option is 'KTJ'.

Question 11

Select the option that is related to the third number in the same way as the second number is related to the first number $102:10405::201:$

Accepted Answer

Correct Option: 40402. To solve this analogy, we first need to determine the relationship between the first pair of numbers, $102$ and $10405$. Step 1: Analyze the first pair. We observe that $102^2 = 10404$. If we add $1$ to this result, we get $10404 + 1 = 10405$. So, the pattern is $text{Number}^2 + 1$. Step 2: Apply the same pattern to the third number. The third number is $201$. Following the pattern, we need to calculate $201^2 + 1$. Step 3: Calculate $201^2$. $201^2 = (200 + 1)^2 = 200^2 + 2 times 200 times 1 + 1^2 = 40000 + 400 + 1 = 40401$. Step 4: Add 1 to the result. $40401 + 1 = 40402$. Step 5: Evaluate the options. Option A: $40402$. This matches our calculated result. Option B: $50402$. This is incorrect as it does not follow the established pattern. Option C: $40401$. This is $201^2$, but the pattern requires adding $1$ to the square. Option D: $50401$. This is incorrect. Therefore, the number that replaces the question mark is $40402$.

Question 12

Select the option that is related to the third term in the same way as the second term is related to the first term MGV: HHA :: LCT :

Accepted Answer

Correct Option: GDY. To solve this letter analogy, we need to find the pattern of transformation from 'MGV' to 'HHA' and then apply the same pattern to 'LCT'. Step 1: Assign numerical positions to the letters of 'MGV' and 'HHA'. For 'MGV': M is $13^{th}$, G is $7^{th}$, V is $22^{nd}$. For 'HHA': H is $8^{th}$, H is $8^{th}$, A is $1^{st}$. Step 2: Determine the pattern for each letter position. First letter: M ($13$) to H ($8$). The difference is $8 - 13 = -5$. Second letter: G ($7$) to H ($8$). The difference is $8 - 7 = +1$. Third letter: V ($22$) to A ($1$). Considering the alphabet wraps around, A can also be $27^{th}$. So, $27 - 22 = +5$. Alternatively, $1 - 22 = -21$. The $+5$ pattern is more common in such series. Thus, the pattern is $(-5, +1, +5)$. Step 3: Apply the pattern to 'LCT'. For 'LCT': L is $12^{th}$, C is $3^{rd}$, T is $20^{th}$. First letter: L ($12$) $- 5 = 7^{th}$ letter, which is G. Second letter: C ($3$) $+ 1 = 4^{th}$ letter, which is D. Third letter: T ($20$) $+ 5 = 25^{th}$ letter, which is Y. So, 'LCT' transforms to 'GDY'. Step 4: Evaluate the options. Option A: HDZ. This is incorrect as it does not follow the established pattern. Option B: GDY. This matches our calculated result. Option C: IDY. This is incorrect. Option D: IDZ. This is incorrect. Therefore, the correct option is 'GDY'.

Question 13

Select the number pair in which the two numbers are related in the same way as are the two numbers of the following number pair: $(28, 65)$

Accepted Answer

Correct Option: $(126, 217)$. To find the related number pair, we need to identify the pattern in the given pair $(28, 65)$. Step 1: Analyze the given pair $(28, 65)$. We can observe that $28$ is close to a cube, $3^3 = 27$. So, $28 = 3^3 + 1$. Similarly, $65$ is close to a cube, $4^3 = 64$. So, $65 = 4^3 + 1$. Thus, the pattern for the pair $(x, y)$ is $(n^3 + 1, (n+1)^3 + 1)$ for some integer $n$. Step 2: Check each option against this pattern. Option A: $(37, 50)$ For $37$: $3^3+1 = 28$, $4^3+1 = 65$. $37$ does not fit the $n^3+1$ form directly (e.g., $3^3+1 = 28$, $4^3+1 = 65$). $37$ is not $n^3+1$ for any integer $n$. Thus, this option is incorrect. Option B: $(2, 10)$ For $2$: $1^3 + 1 = 1^3 + 1 = 2$. So $n=1$. For $10$: According to the pattern, the second number should be $(1+1)^3 + 1 = 2^3 + 1 = 8 + 1 = 9$. However, the given second number is $10$. Thus, this option is incorrect. Option C: $(126, 217)$ For $126$: We know $5^3 = 125$. So, $126 = 5^3 + 1$. Here $n=5$. For $217$: According to the pattern, the second number should be $(5+1)^3 + 1 = 6^3 + 1 = 216 + 1 = 217$. This matches the given second number. This option perfectly fits the established pattern. Option D: $(26, 65)$ For $26$: We know $3^3 = 27$. So, $26 = 3^3 - 1$. This is not $n^3+1$. For $65$: This is $4^3+1$. Since the first number does not follow the $n^3+1$ pattern, this option is incorrect. Therefore, the pair $(126, 217)$ follows the same relationship as $(28, 65)$.

Question 14

Seema walks to her office. She is facing south when she reaches her office. After starting from home, she turned left twice and then right before reaching her office. Which direction was Seema facing when she started from her home?

Accepted Answer

Correct Option: West/पश्चिम. This is a direction sense problem that requires working backward from the final direction. 1. Final Direction: Seema is facing South when she reaches her office. 2. Last Turn: She turned Right just before reaching her office. If she faced South after a right turn, we need to determine what direction she was facing before that turn. A right turn from East leads to South. Therefore, she must have been facing East before her final right turn. 3. Turns Before Last: Before the final right turn, she turned Left twice. So, she was facing East after making two left turns. To find the direction she was facing before these two left turns (i.e., when she started from home), we need to reverse these turns. Reversing a Left turn is equivalent to making a Right turn. So, we need to apply two Right turns from the East direction. First reversed turn (Right from East): If you are facing East and turn Right, you will face South. Second reversed turn (Right from South): If you are facing South and turn Right, you will face West. Therefore, Seema was facing West when she started from her home. To verify, let's trace the path forward: Start: West Turn Left (1st): South Turn Left (2nd): East Turn Right (before office): South This matches the given final direction. Let's analyze why other options are incorrect: A. North: If she started North, after two left turns (West, then South) and one right turn (West), she would face West, not South. B. East: If she started East, after two left turns (North, then West) and one right turn (North), she would face North, not South. C. South: If she started South, after two left turns (East, then North) and one right turn (East), she would face East, not South. Hence, the only consistent starting direction is West.

Question 15

The age of a father is two and a half times the age of his son. Five years ago, the father's age was thrice the age of the son then. What is the age of the son now ?

Accepted Answer

Correct Option: 20 years/20 वर्ष. Let $S$ be the current age of the son and $F$ be the current age of the father. Condition 1: "The age of a father is two and a half times the age of his son." This can be written as an equation: $$ F = 2.5 times S F = frac{5}{2} S quad text{(Equation 1)} $$ Condition 2: "Five years ago, the father's age was thrice the age of the son then." Five years ago: Son's age was $S - 5$. Father's age was $F - 5$. So, the equation is: $$ F - 5 = 3 times (S - 5) quad text{(Equation 2)} $$ Now, we substitute Equation 1 into Equation 2 to solve for $S$: $$ left(frac{5}{2} Sright) - 5 = 3(S - 5) $$ Distribute the 3 on the right side: $$ frac{5}{2} S - 5 = 3S - 15 $$ To eliminate the fraction, multiply the entire equation by 2: $$ 2 times left(frac{5}{2} Sright) - 2 times 5 = 2 times (3S) - 2 times 15 $$ $$ 5S - 10 = 6S - 30 $$ Now, rearrange the terms to solve for $S$. Move $5S$ to the right side and $-30$ to the left side: $$ 30 - 10 = 6S - 5S $$ $$ 20 = S $$ So, the current age of the son is 20 years. Verification: If the son's current age ($S$) is 20 years, then the father's current age ($F$) is $F = frac{5}{2} times 20 = 5 times 10 = 50$ years. Check Condition 1: Is 50 years two and a half times 20 years? Yes, $50 = 2.5 times 20$. Check Condition 2: Five years ago, son's age was $20 - 5 = 15$ years. Father's age was $50 - 5 = 45$ years. Is 45 years thrice 15 years? Yes, $45 = 3 times 15$. Both conditions are satisfied. Let's analyze why other options are incorrect: A. 15 years: If $S=15$, then $F = 2.5 times 15 = 37.5$. Five years ago, son was 10, father was 32.5. $32.5 eq 3 times 10$. B. 10 years: If $S=10$, then $F = 2.5 times 10 = 25$. Five years ago, son was 5, father was 20. $20 eq 3 times 5$. C. 12 years: If $S=12$, then $F = 2.5 times 12 = 30$. Five years ago, son was 7, father was 25. $25 eq 3 times 7$. Thus, the correct age of the son now is 20 years.

Question 16

If '+' stands for '-', '-' stands for 'x', 'x' stands for '÷' and '÷' stands for '+', then what will be the value of the following expression? $14-3+10times5div5$

Accepted Answer

Correct Option: 45. This problem requires us to substitute the given new meanings for the mathematical operators and then evaluate the expression following the standard order of operations (BODMAS/PEMDAS). Given Operator Transformations: + stands for - - stands for x x stands for ÷ ÷ stands for + Original Expression: $14 - 3 + 10 times 5 div 5$ Step 1: Substitute the operators with their new meanings. Replace - with x Replace + with - Replace x with ÷ Replace ÷ with + The expression becomes: $14 times 3 - 10 div 5 + 5$ Step 2: Evaluate the new expression using the BODMAS/PEMDAS order of operations. (Brackets/Parentheses, Orders/Exponents, Division and Multiplication (from left to right), Addition and Subtraction (from left to right)) 1. Division: Perform the division operation first. $10 div 5 = 2$ The expression is now: $14 times 3 - 2 + 5$ 2. Multiplication: Perform the multiplication operation next. $14 times 3 = 42$ The expression is now: $42 - 2 + 5$ 3. Addition and Subtraction (from left to right): Perform these operations in the order they appear. First, subtraction: $42 - 2 = 40$ Next, addition: $40 + 5 = 45$ Therefore, the value of the expression is 45. Let's analyze why other options are incorrect based on the correct calculation: A. 65: This would be obtained if multiplication and addition were prioritized differently or if errors in substitution occurred. For example, if $14 times 3 + 10 times 5 + 5$ was calculated as $42 + 50 + 5 = 97$, or if $14 times 3 - 10 div 5 + 5$ was incorrectly evaluated. B. 48: This value is not reached through the correct order of operations or substitution. D. 40: This is the result before the final addition of 5 ($42 - 2 = 40$). Missing the last step leads to this incorrect answer. The only correct result following the rules is 45.

Question 17

How many triangles are there in the given figure ? दी गई आकृति में कितने त्रिभुज हैं ?

Accepted Answer

Correct Option: 12. The given figure is a large triangle that is divided by lines drawn from its top vertex to the base, and also by a horizontal line parallel to the base. To count the number of triangles systematically in such a figure, we can use a standard method: 1. Count the number of segments on the base: Identify the number of smaller segments formed on the main base (or any horizontal line) by the lines originating from the opposite vertex. In this figure, the lines from the top vertex divide the base into 3 segments. Let $n$ be the number of segments on the base. Here, $n=3$. 2. Count the number of horizontal levels: Identify the number of horizontal lines (including the main base) that act as bases for triangles. In this figure, there are two such horizontal lines: the main base and the internal horizontal line. Let $k$ be the number of horizontal levels. Here, $k=2$. 3. Apply the formula: The total number of triangles in such a configuration is given by the formula: $k times frac{n(n+1)}{2}$. For a single horizontal base with $n$ segments, the number of triangles is $frac{n(n+1)}{2}$. In our case, for $n=3$, this is $frac{3(3+1)}{2} = frac{3 times 4}{2} = frac{12}{2} = 6$. Since there are $k=2$ horizontal levels, we multiply this by 2. Total triangles $= 2 times 6 = 12$. Alternatively, we can list them systematically: A. Triangles with their base on the bottommost horizontal line (main base): Smallest triangles (1 segment base): There are 3 such triangles. Medium triangles (2 segments base): There are 2 such triangles (formed by combining two adjacent small triangles). Large triangles (3 segments base): There is 1 such triangle (the largest one with the bottom base). Total from the bottom base: $3 + 2 + 1 = 6$ triangles. B. Triangles with their base on the middle horizontal line: Similarly, for the middle horizontal line, it is also divided into 3 segments by the lines originating from the top vertex. Smallest triangles (1 segment base): There are 3 such

Question 18

Figure A is embedded in one of the four answer figures. Select the correct alternative. आकृति A, चार उत्तर आकृतियों में से एक में समाहित है सही विकल्प चुनिए

Accepted Answer

Correct Option: . The task is to identify which of the four answer figures contains Figure A embedded within it. Figure A is a specific geometric pattern. Description of Figure A: Figure A consists of a horizontal line segment. From the exact midpoint of this horizontal line, a vertical line segment descends. From the bottom end of this vertical line segment, two diagonal lines diverge downwards and outwards, forming a 'Y' shape with a horizontal bar at the top. Let's examine each option: Option 1: This figure contains an 'X' shape and a small triangle in the bottom right. It does not contain the specific 'Y' shape with a horizontal top bar as seen in Figure A. The lines and their connections do not match the structure of Figure A. Option 2: This figure has a central horizontal line. From its left end, lines extend to the top-left and bottom-left corners. From its right end, lines extend to the top-right and bottom-right corners. This forms a large 'X' pattern with a central horizontal bar. This structure does not contain the specific 'Y' shape with a horizontal top bar of Figure A. Option 3: This figure has a central horizontal line. From its midpoint, a vertical line extends upwards to the top edge and downwards to the bottom edge. From the ends of the horizontal line, lines extend to the top-left and top-right corners. While it has a horizontal and vertical line, the diverging 'Y' arms from the bottom of the vertical line are missing or not in the correct configuration to form Figure A. Option 4: Let's look closely at this figure. It has a central horizontal line. From its midpoint, a vertical line extends upwards to the top edge and downwards to the bottom edge. Crucially, it also has two diagonal lines extending from the bottom end of the central vertical line (which is the bottom edge of the square) to the bottom-left and bottom-right corners of the square. We can find Figure A embedded here: The horizontal line of Figure A corresponds to the central horizonta

Question 19

The given venn diagram represents which of the given alternatives ? वेन आरेख दिए गए विकल्पों में से किस को निरूपित करता है ?

Accepted Answer

Correct Option: Weeks, Years, Months/सप्ताह, वर्ष, माह. The Venn diagram shows three concentric circles, indicating a hierarchical relationship where one category is a subset of another, which in turn is a subset of a larger, encompassing category. This implies a 'contains' or 'is part of' relationship in a nested manner. Let's analyze each option: A. House, Window, Tenant: A window is a part of a house, and a tenant lives in a house. However, a tenant is not a subset of a window, nor is a window a subset of a tenant. This relationship does not fit the concentric containment model where each inner circle is a component of the next larger circle. B. Weeks, Years, Months: This option perfectly fits the concentric diagram. Weeks are a unit of time that constitute Months, and Months are a unit of time that constitute Years. So, the innermost circle would represent Weeks, the middle circle Months (which contain Weeks), and the outermost circle Years (which contain Months). This establishes a clear and consistent hierarchical containment: $text{Weeks} subset text{Months} subset text{Years}$. C. Paragraph, Sentence, Pen: A sentence is a component of a paragraph. However, a pen is an object used for writing and is not contained within a sentence or a paragraph in a hierarchical sense. Thus, this option does not fit the concentric structure. D. Trucks, Ships, Transport: Trucks and Ships are both modes of Transport. This relationship would typically be represented by a larger circle (Transport) containing two separate, non-overlapping circles (Trucks and Ships), as they are distinct types of transport. This is not a concentric, nested relationship. Therefore, the only alternative that accurately represents the given concentric Venn diagram is 'Weeks, Years, Months'.

Question 20

Three different positions of the same dice are shown below. Which number is on the face opposite the face showing 3 ? निम्न किसी पासे की तीन भिन्न स्थितियाँ दर्शाई गई हैं संख्या 3 के विपरीत फलक पर कौन सी संख्या है ?

Accepted Answer

Correct Option: 4. To determine the number opposite 3, we use the rule for dice: If two positions of a die have one common face, then the numbers on the adjacent faces (in the same rotational direction, e.g., clockwise) from the common face are opposite to each other. Let's compare the first two dice positions: Dice 1 (Visible faces: 3, 6, 1) Dice 2 (Visible faces: 6, 4, 5) 1. Identify the common face: The common face between Dice 1 and Dice 2 is 6. 2. Trace clockwise from the common face (6): From Dice 1: $6 to 1 to 3$ From Dice 2: $6 to 5 to 4$ 3. Establish opposite pairs: By comparing the sequences, we find: 1 is opposite 5. 3 is opposite 4. The remaining numbers are 6 and 2, so 6 is opposite 2. Thus, the number on the face opposite 3 is 4. Let's analyze the other options based on this consistent set of opposite pairs: $(1,5)$, $(3,4)$, $(6,2)$. A. Option A (6): From Dice 1, 6 is adjacent to 3 and 1. From our derived pairs, 6 is opposite 2. Therefore, 6 cannot be opposite 3. C. Option C (5): From Dice 2, 5 is adjacent to 6 and 4. From our derived pairs, 5 is opposite 1. Therefore, 5 cannot be opposite 3. D. Option D (2): From Dice 3, 2 is adjacent to 5 and 1. From our derived pairs, 2 is opposite 6. Therefore, 2 cannot be opposite 3. While comparing Dice 1 and Dice 3 might lead to an inconsistency (a common issue in some poorly designed questions), the most direct and clear application of the rule using Dice 1 and Dice 2 consistently yields that 3 is opposite 4, which is available in the options.

Question 21

Seven children A, B, C, D, E, F and G are standing in a queue. E is at the fifth place from left. Only C is between A and B. G is at the first place from right. B is three places after F. What is the position of D from left ?

Accepted Answer

Correct Option: sixth/छठा. Let's represent the seven positions in the queue from left to right as $P1, P2, P3, P4, P5, P6, P7$. 1. "E is at the fifth place from left." $P1 P2 P3 P4 mathbf{E} P6 P7$ 2. "G is at the first place from right." This means G is at the seventh position from the left ($P7$). $P1 P2 P3 P4 mathbf{E} P6 mathbf{G}$ 3. "B is three places after F." This implies that if F is at position $x$, B is at position $x+3$. So, there are two people between F and B ($F B$). Let's test possible positions for F and B: If F is at $P1$, then B is at $P4$. This gives: $mathbf{F} P2 P3 mathbf{B} mathbf{E} P6 mathbf{G}$ If F is at $P2$, then B is at $P5$. This conflicts with E being at $P5$. If F is at $P3$, then B is at $P6$. This gives: $P1 P2 mathbf{F} P4 mathbf{E} mathbf{B} mathbf{G}$ 4. "Only C is between A and B." This means A, C, and B must be in a consecutive block, either $A C B$ or $B C A$. Let's evaluate the two promising scenarios for F and B: Scenario 1: F at $P1$, B at $P4$ Queue so far: $mathbf{F} P2 P3 mathbf{B} mathbf{E} P6 mathbf{G}$ Remaining children to place: A, C, D. Remaining empty slots: $P2, P3, P6$. Now apply "Only C is between A and B": Since B is at $P4$, the sequence $A C B$ would mean A is at $P2$ and C is at $P3$. This fits perfectly. Resulting queue: $mathbf{F} mathbf{A} mathbf{C} mathbf{B} mathbf{E} P6 mathbf{G}$ The children placed are F, A, C, B, E, G. The only remaining child is D. The only remaining empty slot is $P6$. Final arrangement: $mathbf{F} mathbf{A} mathbf{C} mathbf{B} mathbf{E} mathbf{D} mathbf{G}$ Let's verify all conditions with this arrangement: E is at the fifth place from left: Yes, E is at $P5$. Only C is between A and B: Yes, A is at $P2$, C is at $P3$, B is at $P4$. C is between A and B. G is at the first place from right: Yes, G is at $P7$. B is three places after F: Yes, F is at $P1$, B is at $P4$. All conditions are satisfied. Scenario 2: F at $P3$, B at $P6$ Queue so far: $P1 P2 mathbf{F} P4 mathbf{E} mathb

Question 22

In HTML, tags consist of keywords enclosed within :

Accepted Answer

Correct Option: angular brackets / एन्गुलर ब्रैकेट्स. The question asks about the delimiters used to enclose keywords in HTML tags. HTML (HyperText Markup Language) uses a specific syntax for defining elements. Option A, 'Flower brackets' (curly braces {}), are commonly used in many programming languages for defining code blocks, objects, or sets, but not for HTML tags. Option B, 'Angular brackets' ( ), are the fundamental syntax for HTML tags. Every HTML tag, such as , , , etc., begins with . This is the correct answer. Option C, 'Parentheses' (()), are typically used for function arguments, mathematical grouping, or expressing order of operations in various contexts, but not for HTML tags. Option D, 'Square brackets' ([]), are often used for array indexing, list definitions, or attribute selectors in CSS, but not for enclosing HTML tag keywords. Therefore, HTML tags are consistently formed by enclosing keywords within angular brackets.

Question 23

is a set of symbols, keywords and set of rules to construct a statement.

Accepted Answer

Correct Option: Programming language/प्रोग्रामिंग भाषा. The question defines a concept as 'a set of symbols, keywords and set of rules to construct a statement.' Option A, 'Computer program', is a sequence of instructions written in a programming language to perform a specific task. It is the output of using a language, not the language itself. Option B, a 'Programming language', is a formal constructed language designed to communicate instructions to a machine, particularly a computer. It inherently comprises a defined set of symbols (e.g., operators, punctuation), keywords (reserved words with special meaning), and a set of rules (syntax and semantics) that govern how these elements can be combined to form valid statements and expressions. This definition perfectly matches the description in the question. Option C, 'Assemble', is a process, specifically the translation of assembly language into machine code, not a set of symbols, keywords, and rules. Option D, 'Syntax', refers specifically to the set of rules that dictates the correct structure and arrangement of symbols and keywords in a language. While syntax is a crucial component, it is only part of what defines a programming language; the language itself encompasses the symbols and keywords as well. Therefore, 'Programming language' is a more complete and accurate answer.

Question 24

The cell having bold boundary in 'Excel' is called ?

Accepted Answer

Correct Option: Active/सक्रिय. The question describes a visual cue in Microsoft Excel: a cell with a bold boundary. This visual indicator signifies the currently selected cell that is ready for interaction. Option A, 'Relative', typically refers to relative cell references in formulas (e.g., A1), which adjust when copied to other cells. It does not describe the visual state of a selected cell. Option B, an 'Active' cell, is the cell that is currently selected in an Excel worksheet. It is distinguished by a thick, bold border, and its address is displayed in the Name Box. This is precisely what the question describes. Option C, 'Absolute', refers to absolute cell references in formulas (e.g., $A$1), which remain fixed when copied. It is unrelated to the visual selection of a cell. Option D, 'Mixed', refers to mixed cell references (e.g., A$1$ or $A$1), combining relative and absolute components. This also does not describe the visual state of a selected cell. Therefore, the cell with a bold boundary in Excel is known as the active cell.

Question 25

Which of the following is not an Antivirus ?

Accepted Answer

Correct Option: Bagle/बैगले. The question asks to identify which of the listed options is not an antivirus program. Option A, 'Avast', is a widely recognized and popular brand of antivirus software, offering protection against various forms of malware. Option B, 'Trend Micro', is a global cybersecurity software company that develops enterprise security software for servers, cloud environments, networks, and endpoints, including antivirus solutions. Option C, 'Kaspersky' (Kaspersky Lab), is a renowned multinational cybersecurity and antivirus provider, known for its comprehensive security products. Option D, 'Bagle', is not an antivirus program; rather, it is a notorious family of computer worms that first appeared in 2004. These worms are designed to spread through email and network shares, often attempting to disable antivirus software and firewalls. Therefore, 'Bagle' is the correct answer as it is a type of malware, not an antivirus.

Question 26

All the characters that a device can use are called:

Accepted Answer

Correct Option: character set/कैरेक्टर सेट. The question asks for the collective term for all characters that a computer system or device can recognize and process. Option A, 'Character codes', are the numerical values assigned to individual characters within a character set (e.g., the ASCII code for 'A' is 65). They are representations, not the collection of characters itself. Option B, a 'Character set', is a defined collection of characters that a computer or device can recognize, process, and display. Examples include ASCII, ISO-8859-1, and Unicode. This term precisely describes the complete repertoire of usable characters for a device. Option C, 'Keyboard character', refers specifically to characters that can be input using a keyboard. This is a subset of all characters a device might handle, as a device can process and display characters not directly available on a standard keyboard. Option D, 'Character alphabet', refers to the letters of a specific language (e.g., the Latin alphabet). A character set is a much broader concept, encompassing not only alphabetic characters but also numbers, punctuation, symbols, and control characters. Therefore, 'character set' is the most accurate and comprehensive term for all characters a device can use.

Question 27

In an E-R diagram, an entity set is represented by :

Accepted Answer

Correct Option: rectangle/रैक्टेंगल. The question pertains to the graphical representation of components within an Entity-Relationship (E-R) diagram, a high-level conceptual data model used in database design. Option A, a 'rectangle', is the standard symbol used in E-R diagrams to represent an entity set. An entity set is a collection of entities of the same type (e.g., all students, all courses). This is the correct representation. Option B, a 'diamond' shape, is used to represent a relationship set, which describes an association among two or more entity sets. Option C, an 'ellipse' (or oval), is used to represent attributes, which are properties describing an entity or a relationship. Option D, a 'circle', is not a standard symbol for an entity set in E-R diagrams; ellipses are used for attributes. Therefore, in E-R modeling, a rectangle is the designated symbol for an entity set.

Question 28

What is full form of VoIP ?

Accepted Answer

Correct Option: Voice over Internet Protocol/ इंटरनेट प्रोटोकॉल के ऊपर ध्वनि. The question asks for the full form of the acronym 'VoIP'. VoIP is a widely recognized telecommunications technology. Option A, 'Voice of Internet Power', is an incorrect expansion; 'of' and 'Power' are not part of the standard acronym. Option B, 'Voice over Internet Protocol', is the universally accepted and correct full form of VoIP. It refers to a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Option C, 'Voice on Internet Protocol', uses 'on' instead of 'over'. While 'on' might seem plausible, 'over' is the precise and established term used in the technology's name, indicating transmission across or via the Internet Protocol. Option D, 'Very Optimised Internet Protocol', is an entirely incorrect expansion, introducing words not related to the acronym's meaning. Therefore, the accurate and standard full form of VoIP is 'Voice over Internet Protocol'.

Question 29

Which of the following will not advance the slides in a slide show view?

Accepted Answer

Correct Option: Esc key. In a slide show view, the objective is to navigate through the presentation. The question asks which action will not advance the slides. Option A, the 'Esc key', is universally used to terminate or exit the slide show presentation, returning to the editing view or the previous state. It does not advance to the next slide. Option B, the 'Space bar', is a common and convenient key used to advance to the next slide in a presentation. Option C, the 'Enter key', also serves as a command to proceed to the next slide or animation step within a slide. Option D, a 'Mouse button' click (typically the left-click), is one of the most intuitive ways to advance to the next slide or trigger the next animation. Therefore, the 'Esc key' is the only option among those listed that does not advance the slides but rather stops the slide show.

Question 30

When you save to , your data will remain intact even when the computer is turned off.

Accepted Answer

Correct Option: Secondary storage device/द्वितीयक संग्रक यंत्र. The question asks about a storage location where data persists even after the computer is turned off. This characteristic defines non-volatile storage. Option A, 'RAM (Random Access Memory)', is a type of primary storage that is volatile; any data stored in RAM is lost once the power supply is removed. Thus, it does not fit the description. Option B, 'Mother Board', is the main circuit board of a computer that connects all components; it is not a data storage device for user files. Option C, 'Secondary storage device' (e.g., Hard Disk Drive, Solid State Drive, USB flash drive), is specifically designed for long-term, non-volatile data storage. Data saved to these devices remains intact even when the computer is powered off. This perfectly matches the requirement. Option D, 'Primary storage device', generally refers to RAM and CPU cache, which are volatile, or ROM, which is non-volatile but not typically where users save their dynamic data. In the context of saving user data for persistence, secondary storage is the appropriate term. Therefore, saving data to a secondary storage device ensures its integrity after power-off.

Question 31

Select the option that is related to the third word in the same way as the second word is related to the first word. Gardener : Trowel :: Seamstress :

Accepted Answer

Correct Option: scissors/कैंची. The analogy presented is "Gardener : Trowel :: Seamstress : ?". This establishes a relationship where the second term is a primary tool used by the first term (profession). A gardener uses a trowel for tasks like digging and planting. Following this established relationship, we need to identify the primary tool used by a seamstress, who is a person whose profession involves sewing clothes. Option A, 'Scythe', is an agricultural tool primarily used for mowing grass or harvesting crops, not by a seamstress. Option B, 'Crowbar', is a lever tool used for prying or forcing things open, which is unrelated to sewing. Option C, 'Scissors', are an indispensable tool for a seamstress, used for cutting fabric, threads, and patterns. This perfectly matches the established relationship. Option D, 'Saw', is a tool with a toothed blade used for cutting wood or other hard materials, not fabric. Therefore, 'Scissors' is the correct choice as it is the most appropriate tool for a seamstress, maintaining the same relationship as 'Gardener : Trowel'.

Question 32

According to a certain code (I) 'may day zay' means 'good little dog' (II) 'jay cay zay' means 'girl behaves good' (III) 'nay diy cay' means 'girl makes noise' (IV) 'day pay cay' means 'little girl fell' Which word is represented by 'zay'?

Accepted Answer

Correct Option: good. To determine the word represented by 'zay', we must analyze the common elements across the coded statements. From statement (I), 'may day zay' translates to 'good little dog'. From statement (II), 'jay cay zay' translates to 'girl behaves good'. By comparing these two statements, we observe that the common code word is 'zay', and the common English word is 'good'. Therefore, 'zay' represents 'good'. Let's examine the other options: Option A, 'behave', is part of 'girl behaves good' (II), but its corresponding code is not 'zay'. Option B, 'fell', is found in 'little girl fell' (IV), but its code is not 'zay'. Option D, 'dog', is present in 'good little dog' (I), but its code is not 'zay'. Thus, based on consistent comparison, 'good' is the only word represented by 'zay'.

Question 33

A parity bit is

Accepted Answer

Correct Option: used to correct errors/ तर्कसंगत एरर का प्रयोग. A parity bit is an additional bit added to a binary data stream to ensure that the total number of '1's in the stream (including the parity bit) conforms to a specific parity scheme (either even or odd). This mechanism is primarily used for error detection. Option A, 'Used to indicate upper case letter', is incorrect; character case is determined by character encoding standards, not parity bits. Option B, 'The last bit in a byte', and Option C, 'The first bit in a byte', describe a possible position for a parity bit, but not its fundamental purpose or definition. A parity bit's position can vary, and its essence lies in its function, not its location. Option D, 'Used to correct errors'. Strictly speaking, a simple parity bit can only detect an odd number of bit errors; it cannot identify which bit is erroneous or correct it. Error correction typically requires more sophisticated coding schemes (e.g., Hamming codes). However, among the given choices, this option is the only one that relates to the core function of a parity bit, which is error handling. In some simplified contexts, 'correct errors' might be used loosely to encompass the entire process of identifying and addressing errors, even if it only performs detection. Given that the other options are entirely unrelated to the purpose of a parity bit, this option, despite its imprecision regarding 'correction' versus 'detection,' is the most appropriate answer describing its role in data integrity.

Question 34

The process of writing out computer instructions is known as

Accepted Answer

Correct Option: coding / कोडिंग. The question asks for the term describing the process of writing computer instructions. Option A, 'Documenting', refers to the creation of explanatory materials (like comments, user manuals, technical specifications) that describe how a program works or how to use it. It is not the act of writing the instructions themselves. Option B, 'Coding' (or programming), is the direct process of writing computer instructions using a specific programming language (e.g., Python, Java, C++). This precisely matches the description. Option C, 'Compiling', is the process of translating source code written in a high-level programming language into machine code or an intermediate code that a computer can execute. This happens after the coding phase. Option D, 'Assembling', is similar to compiling but specifically refers to the translation of assembly language code into machine code. This also occurs after the instructions have been written in assembly language. Therefore, 'coding' is the correct term for the act of writing computer instructions.

Question 35

The method of internet access that requires a phone line, but offers faster access speeds than dial-up is the connection.

Accepted Answer

Correct Option: Digital Subscriber Line (DSL) / डिजिटल उपभोक्ता पंक्ति. The question describes an internet access method characterized by two key features: it requires a phone line, and it offers faster speeds than dial-up. Option A, 'Cable access', utilizes coaxial cables, typically the same infrastructure used for cable television, not traditional telephone lines. Option B, 'Satellite access', uses a satellite dish to communicate with a satellite in orbit. While some early satellite internet systems might have used a phone line for the return path, the primary data transmission does not rely on it in the way DSL does. Option C, 'Fiber-optic service' (Fiber to the Home/FTTH), uses optical fiber cables to deliver internet, which is distinct from the copper telephone lines. Option D, 'Digital Subscriber Line (DSL)' technology, is specifically designed to provide high-speed internet access over standard copper telephone lines. Unlike dial-up, DSL allows for simultaneous voice calls and provides a much faster, always-on connection, fulfilling both conditions mentioned in the question. Therefore, DSL is the correct connection type that uses a phone line and is faster than dial-up.

Question 36

The attribute specifies (in pixels) the distance between two adjacent cells.

Accepted Answer

Correct Option: Cell spacing / सेल स्पेसिंग. The question asks for the attribute that defines the distance between two adjacent cells, typically in a tabular or grid layout context (e.g., HTML tables). Option A, 'Width', refers to the horizontal dimension of an individual cell or element. It does not define the space between cells. Option B, 'Height', refers to the vertical dimension of an individual cell or element. It also does not define the space between cells. Option C, 'Cell padding', defines the space between the content of a cell and its border. It is an internal spacing within a cell, not the space separating cells from each other. Option D, 'Cell spacing', is the attribute that specifies the amount of space, in pixels, between the borders of adjacent cells in a table. This directly corresponds to the 'distance between two adjacent cells' as described in the question. Therefore, 'Cell spacing' is the correct attribute for controlling the separation between table cells.

Question 37

Pipeline strategy requires :

Accepted Answer

Correct Option: Instruction pre-fetch/निर्देश प्री-फेच. Pipelining is a technique in computer architecture that improves instruction throughput by allowing multiple instructions to be processed in different stages of execution concurrently. To achieve this concurrency and keep the pipeline busy, a continuous flow of instructions is essential. Option A, 'Instruction execution', is a stage within the pipeline, where the actual operation specified by the instruction is performed. While it's part of the pipeline, it's not the requirement that enables the pipelining strategy itself. Option B, 'Instruction pre-fetch' (or instruction fetch), is a critical requirement for pipelining. It involves retrieving instructions from memory ahead of time, before they are needed by subsequent stages of the pipeline (like decode or execute). This ensures that the pipeline stages are always supplied with instructions, minimizing idle time and maximizing throughput. Option C, 'Instruction decoding', is another stage in the pipeline, where the fetched instruction is interpreted to determine the operation to be performed and the operands involved. It's a component of the pipeline, not the overarching requirement for the strategy. Option D, 'Instruction manipulation', is a broad term and not a specific, recognized stage or requirement in the context of CPU pipelining. Instructions are processed and transformed, but 'manipulation' isn't the precise term for a core requirement.

Question 38

Who designed the first electronic computer ENIAC ?

Accepted Answer

Correct Option: Presper Eckert and John W Mauchly/प्रेसपर एर्स्ट और जोन डब्लू. मैकली. The question asks about the designers of ENIAC (Electronic Numerical Integrator and Computer), which was one of the earliest electronic general-purpose digital computers. Option A, 'Von Neumann' (John von Neumann), is renowned for his contributions to the stored-program concept and the Von Neumann architecture, which became fundamental to modern computing. While he was involved in the EDVAC project, which followed ENIAC, he was not the primary designer of ENIAC itself. Option B, 'Joseph M Jacquard', is known for inventing the Jacquard loom in the early 19th century, which used punch cards to control patterns, a concept that later influenced computing, but he was not involved in electronic computers. Option C, 'Presper Eckert and John W Mauchly', were the lead engineers and principal designers of ENIAC at the University of Pennsylvania's Moore School of Electrical Engineering. Their work on ENIAC, completed in 1945, marked a pivotal moment in the history of computing. This is the correct answer. Option D, 'John Napier', was a Scottish mathematician who invented logarithms and Napier's bones in the late 16th and early 17th centuries, long before the advent of electronic computers. Therefore, J. Presper Eckert and John W. Mauchly are correctly credited with designing ENIAC.

Question 39

A device that is connected to the motherboard is called

Accepted Answer

Correct Option: internal device / आन्तरिक यंत्र. The question asks for a term that describes a device connected to the motherboard. This implies components that are physically housed within the computer case and interface directly with the motherboard. Option A, 'External device', refers to components that are connected to the computer from the outside, such as a keyboard, mouse, monitor, or external hard drive. These are not typically described as being 'connected to the motherboard' in the sense of being part of the internal system directly plugged in. Option B, 'Adjunct device', is not a standard technical term in computer hardware for components connected to the motherboard. Option C, 'Peripheral device', is a broader term that refers to any auxiliary device that connects to and works with the computer, but is not part of the core computer architecture (CPU, main memory). This category can include both internal (e.g., internal hard drive, graphics card) and external devices. However, the Hindi translation "परिधीय (बाह्य) यंत्र" explicitly suggests an "external peripheral device", which would make it incorrect for devices inside the case. Option D, 'Internal device', specifically refers to components that are located inside the computer case and are connected to the motherboard. This includes a wide range of components such as RAM modules, the CPU, expansion cards (like graphics or sound cards), internal hard drives, and SSDs. This term accurately encompasses devices that are physically inside and directly connected to the motherboard. Therefore, 'internal device' is the most fitting description for a device connected to the motherboard and residing within the computer's casing.

Question 40

Which of the following is the greatest advantage of co-axial cabling ?

Accepted Answer

Correct Option: Long distances/दीर्घ दूरी. The question asks for the greatest advantage of coaxial cabling. Coaxial cable has been a foundational technology for various networks and transmissions due to its specific characteristics. Option A, 'High security', is not its greatest advantage. While coaxial cable offers better shielding and thus more security against electromagnetic interference and casual eavesdropping than unshielded twisted pair, it is less secure than fiber optic cables and can still be tapped with specialized equipment. Option B, 'Physical dimensions', are often a disadvantage. Coaxial cables are typically thicker, heavier, and less flexible than twisted-pair cables, making them more challenging to install in tight spaces. Option C, 'Long distances', is a significant advantage of coaxial cabling. It can transmit signals over much longer distances than twisted-pair cables without requiring signal amplification or regeneration, due to its superior shielding and lower attenuation characteristics. This was a key benefit in early Ethernet networks and cable television. Option D, 'Easily tapped', is actually a disadvantage, not an advantage. While not as easy to tap as unshielded twisted pair, it is more vulnerable to tapping than fiber optic cables, which are extremely difficult to tap without detection. Therefore, the ability to transmit signals over long distances with less signal degradation is the most prominent advantage of coaxial cabling among the given choices.
