If P denotes ‘×’, Q denotes ‘÷’, R denotes ‘+’, and S denotes ‘-’, then what will come in place of ‘?’ in the following equation?
94 R 16 Q 2 P 7 S 64 R 13 P 2 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 112.
Given conditions: P denotes ‘×’, Q denotes ‘÷’, R denotes ‘+’, and S denotes ‘-’
Given equation: 94 R 16 Q 2 P 7 S 64 R 13 P 2 = ?
After interchanging the expression becomes:
= 94 + (16 ÷ 2) × 7 - 64 + 13 × 2
= 94 + (8 × 7) - 64 + (13 × 2)
= 94 + 56 - 64 + 26
= 176 - 64
= 112
