If M denotes ‘−’, N denotes ‘÷’, O denotes ‘×’ and P denotes ‘+’, then what will come in place of ‘?’ in the following equation?
(16 O 7) P 124 M 92 P (86 N 43) O 18 M 29 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 151
The given equation is: (16 O 7) P 124 M 92 P (86 N 43) O 18 M 29 = ?
M denotes ‘−’, N denotes ‘÷’, O denotes ‘×’ and P denotes ‘+’.
Replacing the letters with their corresponding signs:
(16 × 7) + 124 − 92 + (86 ÷ 43) × 18 − 29
= 112 + 124 − 92 + (2) × 18 − 29
= 112 + 124 − 92 + 36 − 29
= 272 - 92 - 29
= 151
Hence, option 2 is the correct option.
