Question : Directions: If M denotes –, N denotes ÷, O denotes ×, and P denotes +, then what will come in place of (?) in the following equation?
√(169) O √(25) P 48 N 4 M 21 P 32 = ?
Option 1: 86
Option 2: 88
Option 3: 90
Option 4: 92
Correct Answer: 88
Solution :
Given:
√(169) O √(25) P 48 N 4 M 21 P 32 = ?
On replacing the letters with the assigned mathematical signs, the equation becomes –
= √(169) × √(25) + 48 ÷ 4 – 21 + 32
= 13 × 5 + 12 – 21 + 32
= 65 + 12 – 21 + 32
= 109 – 21
= 88
So, 88 is the required answer to the given equation. Hence, the second option is correct.
