Question : Directions: If M denotes –, N denotes ÷, O denotes ×, and P denotes +, then what will come in place of (?) in the following equation?
162 N 6 M $\sqrt[3]{729}$ O 4 P 126 = ?
Option 1: 117
Option 2: 125
Option 3: 121
Option 4: 112
Correct Answer: 117
Solution :
Given:
162 N 6 M $\sqrt[3]{729}$ O 4 P 126 = ?
After replacing the letters with the mathematical signs, we get:
= 162 ÷ 6 – $\sqrt[3]{729}$ × 4 + 126
= 27 – $\sqrt[3]{729}$ × 4 + 126
= 27 – 9 × 4 + 126
= 27 – 36 + 126
= 117
So, 117 is the answer to the given equation. Hence, the first option is correct.
