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 =?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 88.
Given equation: (√169 O √25) P 48 N 4 M 21 P 32 =?
Given conditions:
M denotes -, N denotes ÷, O denotes ×, and P denotes +
After interchanging the expression becomes:
= (√169 × √25) + 48 ÷ 4 - 21 + 32
= (13 × 5) + 48 ÷ 4 - 21 + 32
= 65 + 12 - 21 + 32
= 88
Hence, option 2 is the correct answer.
