Question : Directions: If P denotes ×, Q denotes ÷, R denotes +, and S denotes –, then what will come in place of (?) in the following equation?
$\sqrt[4]{81}$ R 6 P 3 S 26 R 64 = ?
Option 1: 63
Option 2: 65
Option 3: 56
Option 4: 59
Correct Answer: 59
Solution :
Given:
$\sqrt[4]{81}$ R 6 P 3 S 26 R 64 = ?
After replacing the letters with the mathematical signs, we get:
= $\sqrt[4]{81}$ + 6 × 3 – 26 + 64
= 3 + 6 × 3 – 26 + 64
= 3 + 18 – 26 + 64
= 59
So, 59 is the answer to the given equation. Hence, the fourth option is correct.
