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".
