Question 1

Which two numbers (not digits) should be interchanged to make the given equation correct?116 - 92 ÷ 4 + 25 × 2 - 20 = 150

Accepted Answer

Interchange 2 and 4. The equation becomes 116 - 92 ÷ 2 + 25 × 4 - 20. Following BODMAS, calculate 92 ÷ 2 = 46 and 25 × 4 = 100. Then, 116 - 46 + 100 - 20 = 70 + 100 - 20 = 170 - 20 = 150. This matches the right-hand side.

Question 2

8 is related to 512 following a certain logic. Following the same logic, 12 is related to 1728. To which of the following is 15related, following the same logic?(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituentdigits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1and 3 and then performing mathematical operations on 1 and 3 is not allowed)

Accepted Answer

The pattern is that the second number is the cube of the first number. 8³ = 512 and 12³ = 1728. Therefore, 15³ = 3375.

Question 3

In a certain code language, 'VAIN' is written as 'OKBY' and 'VAST' is written as 'UUBY'. How will 'VERB' be written in that language?

Accepted Answer

The pattern is: V becomes next letter (W), A becomes previous (Z), I becomes next (J), N becomes previous (M). Then, reverse the order and shift each letter by +13 (M to Z, J to W, Z to M, W to J). Applying this to VERB gives CTFY.

Question 4

In the following series, only one letter-cluster is incorrect. Select the incorrect letter-cluster.YCG IMQ SVZ CGK MQU

Accepted Answer

The pattern is +8, +6 for each letter. Y(+8)G(+6)C. I(+8)Q(+6)M. C(+8)K(+6)G. M(+8)U(+6)Q. SVZ is incorrect as S(+8)A(+6)G, not Z.

Question 5

Select the option in which the numbers share the same relationship as that shared by the given pair of numbers.(149, 213)(168, 232)(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 – Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Accepted Answer

The relationship is a constant difference. 213 - 149 = 64 and 232 - 168 = 64. Option 3 also has a difference of 64 (217 - 153 = 64).

Question 6

The same operation(s) are followed in all the given number pairs except one. Find that odd number pair.(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 – Operations on 13 such as adding/deleting/multiplying etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Accepted Answer

The pattern is (First number * 3) + 3 = Second number. For 12:39, (12*3)+3=39. For 15:48, (15*3)+3=48. For 13:42, (13*3)+3=42. But for 11:35, (11*3)+3=36, not 35. So, 11:35 is the odd one out.

Question 7

In a certain code language,A # B means A is the sister of B.A @ B means A is the son of B.A & B means A is the wife of B.A % B means A is the father of B.How is Q related to R if P & Q % L # R & K?

Accepted Answer

From P & Q, P is Q's wife. From Q % L, Q is L's father. From L # R, L is R's sister. So, Q is L's father and L is R's sister, making Q the father of R.

Question 8

Six letters U, V, W, X, Y and Z are written on different faces of a dice. Two positions of this dice are shown in the figure below. Find the letter on the face opposite to Z.

Accepted Answer

Identify common faces (U, V). Rotate clockwise from common faces. U-V-W and U-V-Y. Thus, W is opposite Y. Since U and V are common, the remaining faces X and Z must be opposite each other. So, Z is opposite X.

Question 9

Which of the following numbers will replace the question mark (?) in the given series?17, 38, 84, ?, 376, 772

Accepted Answer

The pattern is (previous number * 2) + 4, then (previous number * 2) + 8, then (previous number * 2) + 12, and so on. So, 84 * 2 + 12 = 168 + 12 = 180.

Question 10

Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which is the one that DOES NOT belong to that group?(Note: The odd man out is not based on the number of consonants/vowels or their position in the letter-cluster.)

Accepted Answer

In options 2, 3, and 4, the difference between the alphabetical positions of the first two letters is 2, and between the last two is 4. Option 1 (KJE) does not follow this pattern.

Question 11

The question contains pairs of words that are related to each other in a certain way. Three of the following four word pairs are alike as these have the same relationship and thus form a group. Which word pair is the one that DOES NOT belong to that group?(The words must be considered as meaningful English words and must not be related to each other based on the number of letters/number of consonants/vowels in the word.)

Accepted Answer

The pattern is 'Shape - Number of sides'. Triangle has 3, Pentagon has 5, Square has 4. Hexagon has 6 sides, not 8, making it the odd one out.

Question 12

A square sheet of paper is folded along the dotted lines successively in the directions shown and is then punched in the last. How would the paper look when unfolded?

Accepted Answer

Unfold the paper step-by-step in reverse order of folding. Each unfold creates a mirror image of the punched holes across the fold line. The final pattern will show the holes symmetrically distributed.

Question 13

Select the option that can replace the question mark (?) in the following series.FM61, EK58, DI55, CG52, ?

Accepted Answer

The first letter decreases by 1 (F-1=E, E-1=D, D-1=C, C-1=B). The second letter decreases by 2 (M-2=K, K-2=I, I-2=G, G-2=E). The number decreases by 3 (61-3=58, 58-3=55, 55-3=52, 52-3=49). Thus, the next term is BE49.

Question 14

Which two numbers (not digits) should be interchanged to make the given equation correct?72 - 6 + (18 ÷ 4) + 17 - (22 × 2) = 44

Accepted Answer

Interchange 6 and 4. The equation becomes 72 - 4 + (18 ÷ 6) + 17 - (22 × 2). Following BODMAS, this simplifies to 72 - 4 + 3 + 17 - 44 = 44, which is correct.

Question 15

What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’are interchanged?342 × 18 + 79 − 45 ÷ 3 = ?

Accepted Answer

Interchange the symbols as given: 342 ÷ 18 − 79 + 45 × 3. Apply BODMAS: 19 − 79 + 135. Then, 19 + 135 − 79 = 154 − 79 = 75.

Question 16

Select the triad in which the numbers are related in the same way as are the numbers of the given triads.(16, 33, 67); (19, 39, 79)(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 – Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

Accepted Answer

The pattern is: second number = (first number * 2) + 1, and third number = (second number * 2) + 1. For (22, 45, 91): 22*2+1=45, 45*2+1=91. This matches the given triads.

Question 17

In a certain code language, 'DEMAND' is written as ‘410132144' and 'SUPPLY' is written as '194216161225'.How will'PRODUCT' be written in that language?

Accepted Answer

The pattern is: each letter's positional value is doubled, except for vowels which are replaced by their positional value. Apply this to PRODUCT: P(16*2=32), R(18*2=36), O(15), D(4*2=8), U(21), C(3*2=6), T(20*2=40).

Question 18

‌247is related to‌127following a certain logic. Following the same logic,‌1115is related to‌1130. To which of the following is‌913related to, following the same logic?(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Accepted Answer

The logic involves adding the last two digits of the number to itself: 1115 + 15 = 1130. Similarly, 913 + 13 = 926.

Question 19

In a certain code language,'A + B' means 'A is the mother of B','A - B' means 'A is the father of B','A $ B' means 'A is the son of B','A % B' means 'A is the sister of B','A / B' means 'A is the wife of B' and'A = B' means 'A is the brother of B'.Which of the following means A is the daughter of K?i. A + K / J - P = Dii. J % P = K + A = Diii. K + A / P - D % Jiv. D + K = A / P – J

Accepted Answer

Analyze each option. Option (iii) K + A means K is mother of A. A / P means A is wife of P. This implies A is female and K is her mother, making A the daughter of K.

Question 20

In a certain code language,R + T means ‘R is the sister of T’.R - T means ‘R is the father of T’.R * T means ‘R is the wife of T’.R ÷ T means ‘R is the mother of T’.Based on the above, how is F related to C if A + B – C ÷ D * E – F ÷ G?

Accepted Answer

From A + B – C ÷ D * E – F ÷ G, we deduce the family tree. C is the mother of D. E is the father of F. D is the wife of E. So, D is C's daughter. F is E's child, making F C's daughter's child.
