Q9. What comes next: 1, 1, 2, 3, 5, 8, 13, 21, ?, ?
Answer: 34, 55
The sequence follows the Fibonacci pattern, where each term is the sum of the two preceding terms. After 13 and 21 come 34 and then 55.
Q10. Which interchanges of numbers and signs will make the equation correct? 6 × 2 + 5 = 32
Answer: + and ×, 6 and 2
If + and × are interchanged, the expression becomes 6 + 2 × 5. If 6 and 2 are also interchanged, it becomes 2 + 6 × 5 = 32. This makes the equation correct.
Q11. What should come at the place of question mark? 144, 121, 100, 81, ?, 49
Answer: 64
The numbers are perfect squares in descending order: $12^2, 11^2, 10^2, 9^2, 8^2, 7^2$. Therefore, the missing term is $8^2 = 64$.

Q16. A is B's brother, and B is the mother of C. What is A's relationship to C?
Answer: Maternal uncle
A is B's brother, so A is male and B's sibling. Since B is the mother of C, A is C's maternal uncle.
Q17. Identify the number that should replace the question mark in the sequence: 2, 6, 18, 54, ?
Answer: 162
The sequence is a geometric progression with common ratio 3: 2, 6, 18, 54. So the next term is 54 × 3 = 162.
Q18. Which group does not belong with the others?
Answer: 4, 16, 36
In options A, B, and C, each term is obtained by multiplying by the same number: 2, 4, 8; 3, 9, 27; and 5, 25, 125. In option D, 4 and 16 fit a pattern, but 36 does not continue the same multiplication sequence.
Answer: WKPA
From QDXM to SFYN, each letter is shifted forward by 2 positions: Q→S, D→F, X→Y, M→N. Applying the same +2 shift to UIOZ gives W, K, P, A.
Answer: O
Since M is at one extreme end of Row 2 and O is at the centre, the arrangement of Row 2 can be fixed accordingly. Counting second to the right of M, while M faces north, leads to O.
Q21. B is A's daughter. C is married to B. D is the son of C. How is A related to D?
Answer: Cannot be determined
B is A’s daughter, so A is B’s parent, but A’s gender is not specified. Since C is married to B and D is C’s son, A could be either grandfather or grandmother depending on A’s gender. Therefore, the relation cannot be determined uniquely.
Q22. Choose the option that correctly replaces the question mark in the series: ABDF, CEGH, EHJJ, ?
Answer: GKML
Each position in the group follows a pattern. The first letters are A, C, E, so next is G; the second letters are B, E, H, so next is K; the third letters are D, G, J, so next is M; and the fourth letters are F, H, J, so next is L. Hence the next term is GKML.
Q23. Find the letter-cluster that should fill the blank in the series: ABZ, BCY, CDX, DEW, ?
Answer: EFV
In the series, the first letters go A, B, C, D, so next is E. The second letters go B, C, D, E, so next is F. The last letters go Z, Y, X, W, so next is V.
Answer: Q10: P11: 012
In the first three groups, the items follow a consistent pattern of decreasing letters, increasing numbers, and valid symbols. In the fourth group, the third item is "012", which does not match the letter-number-symbol pattern, so it is the odd one out.
Q25. Choose the number that continues the pattern: 21, 34, 55, ?
Answer: 89
Each term is the sum of the previous two terms: $21+34=55$. Therefore, the next term is $34+55=89$.
Q26. If $6 @ 4 = 40$ and $5 @ 3 = 24$, then what is the value of $8 @ 5$?
Answer: 65
Using the pattern $a @ b = ab + (a+b)$, we get $6 @ 4 = 24+10=34$, which does not fit, so test another relation. The correct pattern is $a @ b = ab + 2(a+b)$: $6 @ 4 = 24+20=44$ still not fit. A better fit from the given values is $a @ b = a^2 + b^2 - 12$? For $6,4$ gives 40 and for $5,3$ gives 22, so not fit. The intended pattern is $a @ b = a^2 + b^2 - ab$; then $6 @ 4 = 36+16-24=28$. Since the options and answer indicate 65, the operation is most likely $a @ b = a^2 + b^2 - a - b$, giving $8 @ 5 = 64+25-8-5=76$, also not fit. Based on the provided answer key, the expected value is 65.
Q27. Find the letter that should come in place of (?) in the series: B, F, J, N, R, V, Z, ?
Answer: D
The letters move forward by 4 positions each time: B, F, J, N, R, V, Z. After Z, moving 4 steps forward gives D. So the missing letter is D.
Q28. Select the letter-cluster that replaces the question mark in the series: RBEH, RGOW, RLYL, RQIA, ?
Answer: RVSP
The letters in each position follow independent patterns. The first letters move forward by 1, 5, 1, 5...; the second letters also follow a repeating shift pattern, and the remaining positions continue accordingly to form RVSP.
Answer: 25
Using the given meanings, the expression becomes 6 × 4 − 24 ÷ 8 + 4. Applying BODMAS gives 24 − 3 + 4 = 25. So the correct answer is 25.
Answer: Nephew
My mother's only son refers to the girl's brother if the speaker is female. The boy is the son of that brother, so he is the girl's nephew.
Answer: 13
The letters of CONTRAST in alphabetical order are A, C, N, O, R, S, T, T. The first letter from the left is A, and the fifth from the right is R. The number of letters between A and R is 13.
Answer: 5: 25: 125
In three triplets, the pattern is: first number squared gives the second, and second number squared gives the third. Only 5: 25: 125 breaks this rule because 25 squared is 625, not 125.
Q33. Identify the term that should replace the question mark: 3, 7, 15, 31, ?
Answer: 63
The sequence follows the pattern of adding 4, 8, 16, ... which doubles each time. So the next addition is 32, giving 31 + 32 = 63.
Answer: (7, 14, 29)
In three groups, each number is double the previous one: 9, 18, 36; 12, 24, 48; and 5, 10, 20. Only 7, 14, 29 breaks the pattern because 14 doubled is 28, not 29.
Answer: 1 and 2
Entries 1 and 2 are exactly the same in every detail. Entry 3 differs by abbreviation and punctuation, and entry 4 has a different surname. Therefore, the identical pair is 1 and 2.
Q36. Seema states, "He is the son of the only daughter of my father." How is the man related to Seema?
Answer: Son
The phrase "the only daughter of my father" refers to Seema. So the man is the son of Seema. Therefore, he is Seema's son.
Q37. Using the same transformation logic, complete the analogy: PLAYING : GNIYALP :: READING : ?
Answer: GNIDAER
In the example, PLAYING becomes GNIYALP by reversing the order of letters. Applying the same rule to READING gives GNIDAER. Therefore, the correct answer is GNIDAER.
Q38. Pick the term that does not belong with the others:
Answer: Windows
Photoshop, Illustrator, and CorelDRAW are all graphics/design software. Windows is an operating system, so it does not belong with the others.

Answer: Mr. Rohit, A - 12 Greenpark, Delhi, 110016
The task is to find the option that matches the given address exactly. Among the choices, option B matches the name, house number, city, and PIN code, with only a minor spacing variation in the locality text as presented in the source.
Q40. Select the option that best completes the analogy: Growth : Stagnation :: Success : ?
Answer: Failure
The analogy is based on antonyms. Since stagnation is the opposite of growth, the corresponding opposite of success is failure.
Answer: Priya Yadav B - 22, Rosewood Heights, Sector 15, Gurgaon, 122002
The first option matches the reference address exactly. The other options differ in either the city name or the pin code.
Answer: 18 ÷ 6 + 3 = 21
Using the code, '÷' means '+', and '+' means '-'. So the option '18 ÷ 6 + 3 = 21' becomes '18 + 6 - 3 = 21', which is true. The other options do not remain correct after substitution.
Q43. Choose the letter-cluster that fits the question mark in the series: PRT, OQS, NPR, ?
Answer: MOQ
Each position in the cluster moves one step backward in the alphabet. So the next term after PRT, OQS, NPR is M O Q? Wait carefully: first letters P, O, N, M; second letters R, Q, P, O; third letters T, S, R, Q. Hence the next cluster is MOQ.
Answer: Three
The letters of LAPTOP in alphabetical order are A, L, O, P, P, T. The fourth from the left is P, and the first from the right is T. The letters between P and T are Q, R, and S, so there are 3 letters.
