Question : Directions: If P denotes ×, Q denotes ÷, R denotes +, and S denotes –, then what will come into place of ? in the following equation?
$\sqrt{256}$ P 3 S 66 Q 11 P 5 R 43 = ?
Option 1: 72
Option 2: 58
Option 3: 61
Option 4: 69
Correct Answer: 61
Solution :
Given:
P denotes ×, Q denotes ÷, R denotes +, and S denotes –
$\sqrt{256}$ P 3 S 66 Q 11 P 5 R 43 = ?
After replacing the letters with given symbols, the equation becomes –
= $\sqrt{256}$ × 3 – 66 ÷ 11 × 5 + 43
= 16 × 3 – 30 + 43
= 48 – 30 + 43
= 61
Therefore, after solving the equation the answer is 61. Hence, the third option is correct.
