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?
(35 P 2) Q 5 S (86 Q 2) R (3 P 15) S 90 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 102.
Given equation: (35 P 2) Q 5 S (86 Q 2) R (3 P 15) S 90 = ?
On replacing the letters:
(35 × 2) ÷ 5 + (86 ÷ 2) - (3 × 15) + 90 = ?
? = 14 + 43 - 45 + 90
? = 147 - 45 = 102
