Reasoning PYQs

The logic followed here is:

Given: PHANTOM → KLSQZLN

Applying this same pattern to SPECTOR:

Therefore, SPECTOR is coded as HTWFZLI.

 

Hence, the correct answer is "Option 3".

The logic followed here is:

Logic: Each letter in the word is shifted +1 in the alphabet, except the 4^th letter, which is shifted by -1.

PEARL → QFBQM

​

Similarly, STONE →

So, STONE is coded as TUPMF.

Hence, the correct answer is "Option 2".

Given: a 40 L solution with salt and water in 3:5 ratio, the amount of salt is 15 L and water is 25 L.

Let x liters of water be added to make the ratio 3:7.

15 divided by (25 + x) = 3 divided by 7

105 = 3 × (25 + x)

105 = 75 + 3x

3x = 30

x = 10

So, 10 L of water should be added.

Hence, the correct answer is Option 1.

The logic followed here is:

Pattern: The value of “A & B” = A² + B²

Now,

1. 3 & 4

= 3² + 4²

= 9 + 16

= 25

2. 5 & 2

= 52 + 22

= 25 + 4

= 29

3) 6 & 3

= 62 + 32

= 36 + 9

= 45

Hence, the correct answer is "Option 3".

Family Chart:

Given: 

Statement: "He is the only son of my mother's only son."

"My mother's only son" → Sohan himself (assuming Sohan is the only son).

"The only son of my mother's only son" → Sohan’s son.

 

So, the man is Sohan’s son.

Hence, the correct answer is "Option 2".

Family Chart:

Given: 

P's brother is Q.

Q is the father of R.

R is the sister of S. 

 

As S's gender is not known yet. So, S's relation to P cannot be determined.

Hence, the correct answer is "Option 4".

The logic followed here is:

After interchanging + & × and 6 & 10, check each option.

Interchange rules: + becomes ×, × becomes +,6 becomes 10,10 becomes 6

Option 1: (6+3)×10 = 36

After interchanging: (10 × 3) + 6 = 36

⇒ 30 + 6 = 36

⇒ 36 = 36

Option 2: (10+2)×6 = 20

After interchanging: (6 × 2) + 10 = 20

⇒ 12 + 10 = 22

⇒ 22 ≠ 20

Option 3: (6+5)×10 = 50

After interchanging: (10 × 5) + 6 = 50

⇒ 50 + 6 = 56

⇒ 56 ≠ 50

Option 4: (10+4)×6 = 30

After interchanging: (6 × 4) + 10 = 30

⇒ 24 + 10 = 34

⇒ 34 ≠ 30

Hence, the correct answer is "Option 1".

BODMAS Table: 

Given expression: 20 M 4 L 3 J 5 = ?

Now, ‘J’ means ‘+’, ‘K’ means ‘−’, ‘L’ means ‘×’ and ‘M’ means ‘÷’

So, the expression becomes: 20 ÷ 4 × 3 + 5

Now apply BODMAS:

⇒ 20 ÷ 4 × 3 + 5

⇒ 5 × 3 + 5

⇒ 15 + 5

⇒ 20

Hence, the correct answer is "Option 1".

BODMAS Table: 

Given equation: 12 + 4 × 2 - 3 = ?

Now, If + = ÷, - = x, x = +,  Then the expression becomes:

⇒ 12 ÷ 4 + 2 × 3 = ?

Now apply BODMAS:

⇒ 12 ÷ 4 + 2 × 3

⇒ 3 + 2 × 3

⇒ 3 + 6

⇒ 9

Hence, the correct answer is "Option 2".

Given numbers: 41 and 36

Sum of 41 and 36 = 41 + 36 = 77

Multiply the sum by 9 → 77 × 9

Calculation:

77 × 9 = (70 × 9) + (7 × 9) = 630 + 63 = 693

Hence, the correct answer is "Option 2".

The logic followed here is:

Logic: The first word is an instrument used to measure the second word.

Here,

Clock : Time → A clock is used to measure time.

Similarly,

Thermometer : Temperature → A thermometer is used to measure temperature.

Hence, the correct answer is "Option 3".

The logic followed here is:

Logic: The first word is the person who files or makes the second word.

Here,

Plaintiff : Complaint → A plaintiff is a person who files a complaint in a court of law.

Similarly,

Petitioner : Petition → A petitioner is a person who files a petition.

Hence, the correct answer is "Option 4.".

The logic followed here is:

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

Hence, the correct answer is "Option 4".

The logic followed here is:

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

Hence, the correct answer is "Option 3".

The logic followed here is:

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

Hence, the correct answer is "Option 3".

The logic followed here is:

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

Hence, the correct answer is "Option 4".

The logic followed here is:

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

Hence, the correct answer is "Option 4".

The logic followed here is:

thus, "153" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

Given: FRIENDLY

Alphabetically:  D, E, F, I, L, N, R, Y

Third from left → F

Second from right → R

Positions:

F = 6

R = 18

So, Letters between them = 18 − 6 − 1 = 11

Hence, the correct answer is "Option 4".

The address given in the problem is,

Amitabh S.

112/44 Block-B, Indira Nagar, Lucknow, 226016

Let's match this address with the given options one by one to figure out which ones are exactly the same.

So, addresses (2), and (3) are exactly identical, while address (1) and (4) is different due to the missing dot and hyphen.

Hence, the correct answer is option (2)
