If ‘P’ stands for ‘÷’, ‘Q’ stands for ‘×’, ‘R’ stands for ‘+’ and ‘S’ stands for ‘-’, what will come in place of the question mark (?) in the following equation?
174 P 2 S 45 R (16 P 4) Q 5 S 26 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 36.
174 P 2 S 45 R (16 P 4) Q 5 S 26 = ?
After interchanging signs,
= (174 ÷ 2) - 45 + (16 ÷ 4) × 5 - 26
= 87 - 45 + (4 × 5) - 26
= 87 - 45 + 20 - 26
= 107 - 45 - 26
= 36
