Reasoning PYQs

Given:

• = ×, − = ÷, × = +, ÷ = −

64 − 4 + 2 × 6

Replace the signs:

64 ÷ 4 × 2 + 6

Calculations:

⇒ 64 ÷ 4 × 2 + 6

⇒ 16 × 2 + 6

⇒ 32 + 6 = 38

∴ The correct answer is "Option 1"

Given: HAT → 8-1-20

Logic: Each letter is replaced by its alphabetical position.

H = 8

A = 1

T = 20

Now for TAH:

T = 20

A = 1

H = 8

Code = 20-1-8

∴ The correct answer is "Option 1".

Given:

BRAVE → CSBWF

Pattern: Each letter is shifted +1 in the alphabet.

B → C

R → S

A → B

V → W

E → F

Apply the same rule to CSBWF:

C → D

S → T

B → C

W → X

F → G

Code = DTCXG

∴ The correct answer is "Option 1"

Given:

A and B are a married pair (A is male).

C is A’s brother.

D is the only son.

D has a sister E.

F’s husband has passed away and B is her daughter-in-law.

Step-by-step relations:

A is married to B.

C is A’s brother.

D and E are the children of C.

B is the daughter-in-law of F → therefore F is the mother of A.

Family Structure:

Relation asked:

C is the father of E.

∴  E is the daughter of C.

Given Series: 4, 5, 12, 39, 163

Check pattern:

4 × 1 + 1 = 5

5 × 2 + 2 = 12

12 × 3 + 3 = 39

Next should follow:

39 × 4 + 4 = 160

But the series has 163 instead of 160.

Hence, the incorrect number is 163.

Reverse coding: Z = 1, Y = 2, … , A = 26

First letter: K

Normal position of K = 11

Reverse position = 27 − 11 = 16

Last letter: E

Normal position of E = 5

Reverse position = 27 − 5 = 22

Sum of reverse positions

16 + 22 = 38

Hence, the correct answer is 38.

Given address:

Flat 404, Block-C, Rajeev Nagar, Patna, Bihar - 800024

Check options:

(1). Flat 404, Block-C, Rajeev Nagar, Patna, Bihar - 800024

→ Exactly the same as the given address ✅

(2). Flat 404, Block-C, Rajeev Nagar, Patna, West Bengal - 800024

→ Different state ❌

(3) Flat 404, Block-C, Rajeev Nagar, Patna, Uttar Pradesh- 800024.

→ Different state ❌

(4) Flat 404, Block-C, Rajeev Nagar, Patna, Jharkhand - 800024

→ Different state ❌

Hence, the correct answer is Option 1.

Given:

Darjeeling seminar = 2 March

Step 1:

Siliguri seminar was 3 days after Darjeeling

2 March + 3 days = 5 March

Step 2:

Kalimpong seminar was 1 day before Siliguri

5 March − 1 day = 4 March

Hence, the correct answer is 4 March.

Observe the pattern:

2 * 3 = 2³ = 8

3 * 4 = 3⁴ = 81

Rule: a * b = aᵇ

Now,

4 * 5 = 4⁵

= 4 × 4 × 4 × 4 × 4

= 1024

Hence, the correct answer is 1024.

Statement: P = Q ≥ S > T = R ≥ U > V

Calculation:

Conclusion I: Q ≥ U ⇒ False (As Q > U)

Conclusion II: T = U ⇒ False (As T > U)

Thus, none of the conclusions is correct.

Hence, the correct answer is option (2).

Given:

P is the father of Q and R.

This means Q and R have the same father.

However, the gender of Q and R is not given, so we cannot say brother or sister exactly.

Therefore, Q and R are siblings.

Hence, Q and R are siblings (brother/sister).

Let’s find the correct pattern.

17 : 4914

17² = 289

289 × 17 = 4913

Then + 1

4913 + 1 = 4914

So the rule is:

n³ + 1

Now apply it to 19:

19³ = 6859

6859 + 1 = 6860

Hence, the correct answer is 6860.

Let’s analyze using standard syllogism logic:

Given Statements

All pens are books → (Pens ⊆ Books)

Some books are novels → (Some overlap between Books and Novels)

Conclusion I: Some pens are novels

No direct link between pens and novels

Just because both connect to books doesn’t guarantee overlap

Conclusion I does NOT follow

Conclusion II: All novels are books

From “Some books are novels”, we cannot say all novels are books

It’s only a partial relation, not universal

Conclusion II does NOT follow

Hence, the correct answer is: Neither I nor II follows

Observe the pattern:

CHINA → FKLQD

C → F (+3)

H → K (+3)

I → L (+3)

N → Q (+3)

A → D (+3)

So the rule is: each letter +3 positions in the alphabet.

Now apply to JAPAN:

J → M

A → D

P → S

A → D

N → Q

So the code becomes MDSDQ.

Hence, the correct answer is MDSDQ.

Step 1: Check letter pattern

Q → R → S → T → U → V

Letters should increase +1 each time.

But after T, the next letter should be U, not V.

Step 2: Check number pattern

2 → 4 → 6 → 8 → 10 → 12

Numbers increase by +2 each time.

So after T8, it should be U10, not V12.

Conclusion

V12 breaks the double-step pattern.

Hence, the pair that does NOT follow the pattern is V12.

1️⃣ Letter pattern

B → Y → C → X

Pattern:

Start letters from beginning: B, C, D, ... (+1)

Alternate letters from end: Y, X, W, ... (−1)

So next letter = D

2️⃣ Number pattern

25 → 2 → 24 → 3

Pattern:

From first group: 25, 24, 23 (−1)

From second group: 2, 3, 4 (+1)

So next number = 23

Result

D23

Hence, the correct answer is D23.

Check the pattern:

3 × 2 = 6

6 × 2 − 1 = 11

11 × 2 − 2 = 20

20 × 2 − 7 = 33 ❌ (should follow a regular pattern)

Instead observe the consistent rule:

3 × 2 = 6

6 × 2 − 1 = 11

11 × 2 − 2 = 20

20 × 2 − 3 = 37

37 × 2 − 4 = 70

So the correct sequence should be:

3, 6, 11, 20, 37, 70

Therefore 33 breaks the pattern.

Hence, the number that breaks the pattern is 33.

Analysis:

Bhajan → devotional music

Qawwali → devotional music

Ghazal → musical/poetic form

Rangoli → decorative floor art (not music)

Three are forms of music, while one is visual art.

Hence, the correct answer is Rangoli (Option 4).

Observation (differences):

9 − 4 = 5

19 − 9 = 10

39 − 19 = 20

79 − 39 = 40

Pattern: differences are doubling

5, 10, 20, 40, next = 80

Calculation:

Next term = 79 + 80 = 159

Hence, the correct answer is 159.

Given:

Sum doubles in 5 years

Interest type = Simple Interest

Let Principal = P

Amount after 5 years = 2P

Formula used:

Simple Interest Amount formula:

A = P × (1 + (R × T) / 100)

Calculation:

Since the sum doubles,

2P = P × (1 + (R × 5) / 100)

Divide both sides by P:

2 = 1 + (5R / 100)

2 − 1 = 5R / 100

1 = 5R / 100

R = (100 × 1) / 5

R = 20

Hence, the correct answer is 20% per annum.
