The logic followed here is:

Logic: Each letter is shifted forward by 1 in the English alphabet.

For, READ → SFBE

Similarly, for BOOK → ?

So, BOOK → CPPL 

Hence, the correct answer is Option 1.

The logic followed here is:

Logic: Using the simple interest formula: Amount = Principal + Principal × Rate × Time

Given:

Amount becomes 2.5 times the principal in 10 years

Amount = 2.5 × Principal

Simple Interest = Amount - Principal = 2.5P - P = 1.5P

Using SI = Principal × Rate × Time:

1.5P = P × R × 10

R = 1.5 / 10 = 0.15

Hence, the correct answer is Option 3.

Family Chart:

Given: 

X and Y are brothers → They are sons of A.

Z is the wife of Y.

B is the daughter of Z → Since Z is Y’s wife, B is the daughter of Y and Z.

So, B is the granddaughter of A.

Hence, the correct answer is "Option 2".

The logic followed here is:

Logic: The operation "$" is defined as a $ b = a² - b

Given: a $ b = 2 → a² - b = 2 → b = a² - 2

Check each option:

Option 1) a = 2, b = 2 → 2² - 2 = 4 - 2 = 2 

Option 2) a = 8, b = 1 → 8² - 1 = 64 - 1 = 63 

Option 3) a = 4, b = 5 → 16 - 5 = 11 

Option 4) a = 9, b = 6 → 81 - 6 = 75 

Hence, the correct answer is Option 1$.

The logic followed here is:

Find the sum of 42 and 42 → 42 + 42 = 84

Multiply the sum by 4 → 84 × 4 = 336

Hence, the correct answer is Option 3.

The logic followed here is:

Given:

In the sentence "The quantum universe expands silently into infinity," the 2^nd words are quantum, expands, into.

Then, The 3^rd letters of these words are a, p, t.

Thus, Combining them gives the word apt.

Hence, the correct answer is Option 4) apt.

The logic followed here is:

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

Hence, the correct answer is "Option 1".

The logic followed here is:

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

Hence, the correct answer is "Option 1".

BODMAS Table: 

Given expression: 5 (7 S 3) D 3 (8 P 6) V 7 D 11 (3 S 13 S 2) P 2 (41 S 9) = ?

Now, if ‘P’ means ‘+’, ‘D’ means ‘-’, ‘S’ means ‘×’, and ‘V’ means ‘÷’, then:

⇒ 5 (7 × 3) - 3 (8 + 6) ÷ 7 - 11 (3 × 13 × 2) + 2 (41 × 9)

⇒ 5 (21) - 3 (14) ÷ 7 - 11 (78) + 2 (369)

⇒ 105 - 42 ÷ 7 - 858 + 738

⇒ 105 - 6 - 858 + 738

⇒ 99 - 858 + 738

⇒ -759 + 738

⇒ -21

Hence, the correct answer is "Option 3".

The logic followed here is:

thus, "445" will replace the question mark in the given series.

Hence, the correct option is "Option 1".
