Back to paper

If P denotes '×', Q denotes '÷', R denotes '+', and S denotes '-', then what will come in place of '?' in the following equation?

256\sqrt{256} P 3 S 66 Q 11 P 5 R 43 = ?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 61.

Given conditions: P denotes '×', Q denotes '÷', R denotes '+', and S denotes '-'

Given equation:  256\sqrt{256} P 3 S 66 Q 11 P 5 R 43 =?

After interchanging the expression becomes:

= 256\sqrt{256} × 3 - 66 ÷ 11 × 5 + 43

= 256\sqrt{256} × 3 - 6 × 5 + 43

= 16 × 3 - 30 + 43

= 48 - 30 + 43 = 61
