Why this answer is correct

Logic followed here is substituting the letters with their respective mathematical operations and then applying the BODMAS rule to solve the expression.

Symbol Mapping:

ABCD
÷×+−

Given equation:

72 A 4 C 6 B 9 D 20 A 2 C 88 A 8 D 15 = ?

Replacing the letters with their respective signs, we get:

72 ÷ 4 + 6 × 9 - 20 ÷ 2 + 88 ÷ 8 - 15 = ?

⇒ 18 + 54 - 10 + 11 - 15 = ?

⇒ 83 - 25 = ?

⇒ 58 = ?

Therefore, the value that will come in place of the question mark is 58.

Hence. the correct answer is "Option 2".

(Left) 9 3 8 7 9 4 8 6 2 5 9 3 6 5 1 2 6 1 5 8 3 9 9 6 8 8 3 9 (Right)

Logic followed:

We need to find perfect squares which are:

Immediately preceded by an odd number

Immediately followed by an even number

Perfect squares among single-digit numbers are: 1, 4, 9

Required pattern:

Odd Number → Perfect Square → Even Number

Checking the series:

(Left) 9 3 8 7 9 4 8 6 2 5 9 3 6 5 1 2 6 1 5 8 3 9 9 6 8 8 3 9 (Right)

Perfect squares satisfying the condition are:

→ 9 in (7 9 4)

→ 4 (in 9 4 8)

→ 1 (in 5 1 2)

→ 9 (in 9 9 6)

Thus, the number of such perfect squares is 4.

Therefore, the answer is More than three.

Hence, the correct answer is "Option 4".
