If M denotes '-', N denotes '÷', O denotes '×', and P denotes '+', then what will come in place of '?' in the following equation?

21 O 5 P 69 N 3 P 225\sqrt{225} M 88 =?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 55.

Given conditions: M denotes '-', N denotes '÷', O denotes '×', and P denotes '+

Given the equation: 21 O 5 P 69 N 3 P 225\sqrt{225} M 88 =?

After interchanging the expression becomes:

= 21 × 5 + 69 ÷ 3 + 225\sqrt{225} - 88

= 105 + 23 + 225\sqrt{225} - 88

= 105 + 23 + 15 - 88

= 143 - 88

= 55
