If P denotes '×', Q denotes '÷', R denotes '+', and S denotes '-', then what will come in place of '?' in the following equation?
R 6 P 3 S 26 R 64 =?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 59.
Given conditions: P denotes '×', Q denotes '÷', R denotes '+', and S denotes '-'
Given equation: R 6 P 3 S 26 R 64 =?
After interchanging the expression becomes:
= ( ) + (6 × 3) - 26 + 64
= 3 + 18 - 26 + 64
= 85 - 26
= 59
