Question : Directions: If P denotes ×, Q denotes ÷, R denotes +, and S denotes –, then what will come in place of (?) in the following equation?
94 R 16 Q 2 P 7 S 64 R 13 P 2 = ?
Option 1: 120
Option 2: 118
Option 3: 108
Option 4: 112
Correct Answer: 112
Solution :
Given:
94 R 16 Q 2 P 7 S 64 R 13 P 2 = ?
After replacing the letters with the mathematical signs, we get –
= 94 + 16 ÷ 2 × 7 – 64 + 13 × 2
= 94 + 8 × 7 – 64 + 13 × 2
= 94 + 56 – 64 + 26
= 112
So, 112 is the answer to the given equation. Hence, the fourth option is correct.
