Reasoning PYQs

Logic used here:

Centre code = First three digits of roll number

Calculation:

817129 ⇒ 817

817131 ⇒ 817

⇒ Same centre code

 

184843 ⇒ 184

184320 ⇒ 184

⇒ Same centre code

 

908325 ⇒ 908

908187 ⇒ 908

⇒ Same centre code

Thus pairs with same examination centre:

817129 & 817131

184843 & 184320

908325 & 908187

∴ The correct answer is option (1).

The least possible Venn diagram for the given statements is as shown below :

Conclusions:

I. Some humans are creators → Follow (As some humans are artists and all artists are creators. As some part of human is common with artist which whole comes in creators, therefore it is true.)

II. All creators are artists → Does not follow (As all artists are creators. So it is possible but not definite.)

∴ Here, Only I follows.​

Hence, the correct answer is "Option 1".

The least possible Venn diagram for the given statements is as shown below :

Conclusions:

I. No A is D → Does not follow (As some A are B, all B are C and no C is D. As no direct relation is given between A and D, therefore it is false.)

II. Some B are not D → Follow (As all B are C and no C is D. As whole B comes in C which cannot be D, therefore it is true.)

∴ Here, Only II follows.​

Hence, the correct answer is "Option 2".

Given:

Series: D, H, L, P, ?

Logic used here:

Alphabet position increases by +4 each step

⇒ P + 4 = T

∴ The correct answer is option (2).

Given:

A word can be formed only if its letters exist in the given word with equal or fewer frequency.

Calculation:

INTELLIGENCE

Check Gene

⇒ All letters available

⇒ O not present ❌

Check Can

⇒ A not present ❌

Check Come

⇒ O not present ❌

∴ The word formed Gene (Option 1).

Given:

GANDHI → HBOEIJ

Logic used here:

Each letter shifts +1 forward in the English alphabet.

Similarly for NEHRU:

N → O , E → F , H → I , R → S , U → V

⇒ NEHRU → OFISV

∴ The correct answer is option (2).

The logic followed here is:

Hence, the correct answer is "Option 4".

Given:

Series = 5, 11, 23, 47, ?

Logic use here:

Pattern: Multiply by 2 and add 1

Calculation:

5 × 2 + 1 = 11

11 × 2 + 1 = 23

23 × 2 + 1 = 47

⇒ 47 × 2 + 1

⇒ 94 + 1

⇒ 95

∴ The corrct answer is option (4).

Given:

256 : 4096 :: 225 : ?

Logic used here:

⇒ Pattern: n2 → n3

256 = 16²

4096 = 16³

225 = 15²

⇒ 15³ = 15 × 15 × 15

⇒ 3375

∴ The corrct answer is option (1).

Given:

Series = 31, 63, 127, 255, 511, ?

Logic used here:

Pattern: Multiply by 2 and add 1

Calculation:

31 × 2 + 1 = 63

63 × 2 + 1 = 127

127 × 2 + 1 = 255

255 × 2 + 1 = 511

⇒ 511 × 2 + 1

⇒ 1022 + 1

⇒ 1023

∴ The correct answer is option (1).

According to the question:

Thus, 'apple grapes banana' is coded as 'abc, jkl, def'.

Hence, "Option 3" is the correct answer.

Given:

Cost Price (CP) = ₹80

Profit = 20%

Formula used:

Selling Price = CP × (100 + Profit%) / 100

Calculation:

SP = 80 × (100 + 20) / 100

⇒ 80 × 120 / 100

⇒ 96

∴ The correct answer is option (1).

Given:

Initial people = 9

Contribution per person = ₹45

People left = 3

Remaining people = 9 − 3 = 6

Formula used:

Total amount = Number of people × Contribution

Calculation:

Total amount collected initially

⇒ 9 × 45

⇒ 405

Remaining people = 6

Required contribution per person

⇒ 405 ÷ 6

⇒ 67.5

∴ Each person must now pay ₹67.5

Given:

Series = 1, 3, 6, 10, 15, ?

Logic used here:

Difference of between numbers 2,3,4,5,6.

1 + 2 = 3

3 + 3 = 6

6 + 4 = 10

10 + 5 = 15

⇒ 15 + 6 = 21

∴ The corrct answer is option (2).

Logic used here:

Each letter is replaced by the next letter in the English alphabet.

Calculation:

COLD

⇒ COLD → DPME

HEAT

⇒ HEAT → IFBU

∴ HEAT will be coded as IFBU.

Given:

First letter = H

Last letter = P

Calculation:

Position of H = 8

Position of P = 16

⇒ Middle position = (8 + 16)

24/2 = 12

12^th letter = L

∴ L lies exactly between H and P.

Given:

Original Address:

Villa No. 5, Green Meadows, Bannerghatta Road, Bengaluru, Karnataka - 560076

Formula used:

Match all details exactly:

⇒ House No.

⇒ Area Name

⇒ Road Name

⇒ State

⇒ PIN Code

Calculation:

Option 1: Karnataka - 560076 ✔

Option 2: Andhra Pradesh - 560076 ✘

Option 3: Tamil Nadu - 560076 ✘

Option 4: Kerala - 560076 ✘

∴ Correct answer is Option 1.

Given:

Indore seminar = 8 April

Indore = 3 days before Surat

Nashik = 2 days after Surat

Formula used:

Surat Date = Indore Date + 3 days

Nashik Date = Surat Date + 2 days

Calculation:

Surat Date

⇒ 8 April + 3 days = 11 April

Nashik Date

⇒ 11 April + 2 days = 13 April

∴ Seminar in Nashik was held on 13 April.

Given:

Series: 9, 14, 24, 39, 59, ?, 114

Formula used:

Pattern: Increasing by +5, +10, +15, +20, +25, +30

Calculation:

14 − 9 = 5

24 − 14 = 10

39 − 24 = 15

59 − 39 = 20

Next increase = 25

⇒ ? = 59 + 25 = 84

Check:

114 − 84 = 30 ✔

∴ Missing number = 84

Given:

Statement: P > Q < S > T = R ≥ U > V

Formula used:

Basic inequality chain comparison

Calculation:

P > Q

S > Q

S > T

T = R

R ≥ U

U > V

⇒ S > T = R ≥ U > V

⇒ S > V

⇒ V < S ✔

Conclusion I is TRUE.

P > Q and S > T

No direct relation between P and T

⇒ P > T cannot be determined ✘

Conclusion II is NOT definitely TRUE.

∴ Only Conclusion I is TRUE.
