Reasoning PYQs

Given

Ganga, Brahmaputra and Yamuna are rivers of India, whereas Amazon is a river in South America.

Hence the correct option is Option 3.

Given Series:

AZ, CY, EX, GW, ?

Observing the pattern:

First letters:

A, C, E, G → Each increases by 2 positions.

Next letter after G = I

Second letters:

Z, Y, X, W → Each decreases by 1 position.

Next letter after W = V

So, the next term = IV

Hence, the correct answer is Option 4.

Given Series

13 + 3 = 16

16 × 2 = 32

32 + 3 = 35

35 × 2 = 70

The pattern is:

+3, ×2, +3, ×2 ...

Continuing the pattern

70 + 3 = 73

Hence, the correct option is Option 1.

Given:

Principal (P) = ₹10,000

Rate of Interest (R) = 8% per annum

Time (T) = 2 years

Formula for Compound Interest:

Amount = P (1 + R/100)^T

Calculation:

Amount = 10000 (1 + 8/100)²

= 10000 (1.08)²

= 10000 × 1.1664

= 11,664

Hence, the correct answer is Option 1.

Given:

FIGHT = EJHIS

Finding the pattern:

F → E (−1)

I → J (+1)

G → H (+1)

H → I (+1)

T → S (−1)

First and last letters −1, middle letters +1.

Applying the same logic to BRAVE:

B → A (−1)

R → S (+1)

A → B (+1)

V → W (+1)

E → D (−1)

BRAVE = ASBWD

Hence, the correct answer is Option 3.

Given:

A number is divisible by both 5 and 9.

Checking options:

35 → Not a multiple of 9

90 → multiple of  both 5, 9

47 → Not a multiple of 9

60 → Not a multiple of 9

Hence, the correct answer is Option 2.

Given:

WORLD = 23-15-18-12-4

Finding the logic:

W = 23

O = 15

R = 18

L = 12

D = 4

Each letter is coded according to its position in the English alphabet.

Applying the same logic to DORLW:

D = 4

O = 15

R = 18

L = 12

W = 23

DORLW = 4-15-18-12-23

Hence, the correct answer is Option 1.

Given statement: Pointing to a photograph, Rohan said, "He is the only son of my father's only daughter.

Case 1) If Rohan is a male member

Case 2) If Rohan is a female member

So, person in the photograph is Rohan's either nephew or son. As out of all the options "Nephew" is given. Therefore case 2 is eliminated.

Thus, person in the photograph is Rohan's nephew.

Hence, 'option 2' is the correct answer.

Given:

MARKET = NBSLFU

Finding the pattern:

M → N (+1)

A → B (+1)

R → S (+1)

K → L (+1)

E → F (+1)

T → U (+1)

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

Applying the same logic to NBSLFU:

N → O

B → C

S → T

L → M

F → G

U → V

Hence, the correct answer is Option 1.

Given Series:

11, 13, 17, 19, 23, ?

Observing the pattern:

11 → Prime number

13 → Prime number

17 → Prime number

19 → Prime number

23 → Prime number

All numbers are consecutive prime numbers.

The next prime number after 23 is 29.

Hence, the correct option is Option 2.

Given

The summit in Ahmedabad was on 10^th January.

Kolkata hosted it five days later.

Calculation:

10^th January + 5 days = 15^th January

Hence, the correct answer is Option 2.

Given Address:

Room 405, PG Block, NIT Trichy, Thuvakudi, Tamil Nadu - 620015

Checking Options

1. Room 405, PG Block, NIT Trichy, Thuvakudi, Tamil Nadu - 620015

Exact match with the given address.

2. Room 405, PG Block, NIT Trichy, Thuvakudi, Tamil Nadu - 620016

PIN code is different.

3. Room 405, PG Block, NIT Trichy, Thuvakudi, Tamil Nadu - 620017

PIN code is different.

4. Room 405, PG Block, NIT Trichy, Thuvakudi, Tamil Nadu - 620018

PIN code is different.

Hence, the correct answer is Option 1.

Given:

2 # 3 = 13

3 # 4 = 25

2 # 3 = (2² + 3²)

= 4 + 9 = 13

3 # 4 = (3² + 4²)

= 9 + 16 = 25

Applying the same logic:

4 # 5 = (4² + 5²)

= 16 + 25

= 41

Hence, the correct answer is Option 2.

Given:

A & B = A × B − A

To find: 7 & 5

Substitute the values:

7 & 5 = 7 × 5 − 7

= 35 − 7

= 28

Hence, the correct answer is Option 1.

Given Equation:

20 ÷ 5 + 6 × 2 − 4 = 18

Solve using BODMAS:

Option 1: Swap ÷ and ×

20 × 5 + 6 ÷ 2 − 4

= 100 + 3 − 4

= 99 (Not correct)

Option 2: Swap + and −

20 ÷ 5 − 6 × 2 + 4

= 4 − 12 + 4

= -4 (Not correct)

Option 2: Swap ÷ and −

20 − 5 + 6 × 2 ÷ 4

= 15 + 12 ÷ 4

= 15 + 3

= 18

Option 4: Swap + and ×

20 ÷ 5 × 6 + 2 − 4

= 4 × 6 + 2 − 4

= 24 + 2 − 4

= 22 (Not correct)

Hence, the correct answer is Option 3.

Given Options:

1. 4321

2. 5432

3. 6543

4. 1234

4321 → digits in descending order 

5432 → digits in descending order 

6543 → digits in descending order 

1234 → digits in ascending order 

First three numbers follow descending order pattern, while 1234 follows ascending order.

Hence, the correct answer is Option 4.

Given Options:

1. Thiruvananthapuram

2. Imphal

3. Guwahati

4. Ranchi

Observation:

Thiruvananthapuram, Imphal and Ranchi are capital cities of their respective states (Kerala, Manipur and Jharkhand).

Guwahati is not the capital of Assam (the capital is Dispur).

Hence, the correct option is Option 3.

Given Number:

7846921453

Modify the digits

Rule:

Increase each even digit by 1.

Decrease each odd digit by 1.

7 → 6,8 → 9,4 → 5,6 → 7,9 → 8,2 → 3,1 → 0,4 → 5,5 → 4,3 → 2

New numbers: 6, 9, 5, 7, 8, 3, 0, 5, 4, 2

Arrange in descending order

9, 8, 7, 6, 5, 5, 4, 3, 2, 0

Take the first five digits from the left end

9, 8, 7, 6, 5

sum = 9 + 8 + 7 + 6 + 5 = 35

Hence, the correct answer is "Option 1".

Given: DF : GI :: KM : ?

Find the pattern

D → G ( +3 )

F → I ( +3 )

Each letter is moved 3 positions forward in the alphabet.

Apply the same rule to KM

K → N ( +3 )

M → P ( +3 )

NP

Hence the correct option is Option 2.

Logic followed here:

2^nd number = (1^st number)³ - 1^st number

3 : 24

3³ - 3 = 27 - 3 = 24

Similarly, 5 : ?

? = 5³ - 5 = 125 - 5 = 120

Hence, the correct answer is Option 2.
