Reasoning PYQs

Decoding signs:

Given: 15 W 3 X 2 Y 4=?

15 W 3 X 2 Y 4=? ⇒ 15 ÷ 3 + 2 - 4=?

⇒ 15 ÷ 3 + 2 - 4=?

⇒ 5 + 2 - 4=?

⇒ 7 - 4=?

⇒ 3 = ?

Hence, "Option 2" is the correct answer.

Given: A's father's wife's only daughter is B.

A is the sibling of B

Hence, the correct option is Option 3.

From the given information

Given: Introducing a boy, a girl says, "He is the son of my mother's only son."

Thus, the boy is girl's nephew.

Hence, the correct option is Option 3.

Given:

1. A is the wife of B.

2. B is the brother of C.

3. C is the father of D.

Thus, A is D's aunt.

Hence, the correct answer is "Option 1".

Decoding signs:

Given: 50 + 10 - 5 × 5 = ?

50 + 10 - 5 × 5 = ? ⇒ 50 - 10 + 5 ÷ 5 = ?

⇒ 50 - 10 + 5 ÷ 5 = ?

⇒ 50 + 1 - 10 = ?

⇒ 51 - 10 = ?

⇒ 41 = ?

Hence, "Option 1" is the correct answer.

The logic followed here is:

Hence, the correct answer is "Option 4".

The logic followed here is:

So, 'RUI' will replace the question mark in the given series.

Hence, the correct answer is "Option 3".

The logic followed here is:

Pattern: Each term = (previous term × previous term) − (previous term − 1)

Check the sequence:

1 → 2 → 1×1 +1 = 2 

2 → 5 → 2×2 +1 = 5 

5 → 26 → 5×5 +1 = 26 

Similarly,

next term = 26 × 26 + 1 = 676 + 1 = 677

Hence, the correct answer is "Option 1".

The logic followed here is:

Check the numbers: 29, 31, 47, 101

All numbers are prime numbers (divisible only by 1 and themselves).

Check the options:

Option 1) 111 → Not prime (divisible by 3, 37) 

Option 2) 103 → Prime 

Option 3) 147 → Not prime (divisible by 3, 7, 7) 

Option 4) 196 → Not prime (divisible by 2, 98) 

So, the number similar to the given sequence is 103.

Hence, the correct answer is "Option 2".

Given:

Statement:

The government has decided to implement stricter regulations on industrial pollution to curb the growing environmental concerns.

Assumptions:

I. Industrial pollution is a significant cause of environmental degradation – True (The decision to regulate industrial pollution assumes it significantly affects the environment).

II. Stricter regulations will reduce industrial pollution – True (Implementing stricter regulations assumes they will have the intended effect).

III. Environmental concerns are primarily related to industrial activities – False (The statement does not assume that all environmental concerns are only due to industrial activities; other sources may exist).

So, Only assumptions I and II are implicit.

Hence, the correct answer is "Option 1".

Given word: COMFORT

Arrange letters in alphabetical order:

C, F, M, O, O, R, T

Check each letter’s position in the original word vs alphabetical order:

Original: C O M F O R T

Alphabetical: C F M O O R T

Positions unchanged: C (1), M (3), O (5), R (6), T (7) → 5 letters

Hence, the correct answer is "Option 4".

The address given in the problem is,

Flat No. 12B, Building 7, Sector 15, Sohna Road, Gurgaon, Haryana - 122001

Now, match this address with the given options:

So, address Option 4 is exactly identical to the given address.

Hence, the correct answer is option 4.

Given word: SCHOOL

First, second, third, and fifth letters of SCHOOL → S, C, H, O

We need to form meaningful four-letter words using S, C, H, O (each letter used once).

Check possible meaningful words:

COSH → Yes, a word

HOSC → No

SCHO → No

CHOS → No

OCHS → No

HOCS → No

Only COSH is meaningful.

Hence, the correct answer is "Option 1".

Given:

Amit is 12^th from the left.

Sunil is 15^th from the right.

After they interchange their positions, Amit becomes 17^th from the left.

That means Sunil’s original position from the left was 17.

Now, If a person is 17^th from the left and 15^th from the right, then

Total persons = 17 + 15 − 1

= 32 − 1

= 31

So, total number of persons in the row is 31.

Hence, the correct answer is "Option 3".

The logic followed here is:

CUT : BDTVSU

Similarly,

TIP : ?

Hence, the correct answer is "Option 2".

The logic followed here is:

WRITE : JEVGR

Similarly,

WRONG : ?

Hence, the correct answer is "Option 1".

The logic followed here is:

Check the series: 1, 4, ___, 16, 25

These are perfect squares:

1 = 1²

4 = 2²

? = 3² = 9

16 = 4²

25 = 5²

So, the missing number is 9.

Hence, the correct answer is "Option 3".

The logic followed here is:

Check the pattern in each group:

Option 1: M1$ : N2# : O3@

Letters: M → N → O (consecutive) 

Numbers: 1 → 2 → 3 (consecutive) 

Symbols: $, #, @ (pattern changes, but consistent as sequence of symbols) 

Option 2: P4% : Q5^ : R6&

Letters: P → Q → R (consecutive) 

Numbers: 4 → 5 → 6 (consecutive) 

Symbols: %, ^, & (pattern consistent) 

Option 3: S7 : T8( : U9)*

Letters: S → T → U (consecutive) 

Numbers: 7 → 8 → 9 (consecutive) 

Symbols: *, (, ) (pattern consistent) 

Option 4: V10_ : X11@ : Y13#

Letters: V → X → Y (not consecutive; skips W) 

Numbers: 10 → 11 → 13 (not consecutive; skips 12) 

Symbols: _, @, # (pattern okay)

So, Option 4 breaks the letter and number sequence pattern.

Hence, the correct answer is "Option 4".

Given: A hexagon has 6 sides.

Number of diagonals =  n × (n − 3) ÷ 2

= 6 × (6 − 3) ÷ 2

= 6 × 3 ÷ 2

= 18 ÷ 2

= 9

Hence, the correct answer is Option 1.

The logic followed here is:

Pattern: A @ B = A² + B

Check:

5 @ 1 = 25 + 1 = 26 

3 @ 4 = 9 + 4 = 13 

Similarly, 6 @ 2 = 36 + 2 = 38

Hence, the correct answer is "Option 2".
