Question : Directions: If A denotes +, B denotes ×, C denotes –, and D denotes ÷, then what will come in place of (?) in the following equation?
124 D 4 C 86 D 2 A 61 A 17 B 3 = ?
Option 1: 100
Option 2: 98
Option 3: 92
Option 4: 110
Correct Answer: 100
Solution :
Given:
124 D 4 C 86 D 2 A 61 A 17 B 3 = ?
After replacing the letters with the mathematical signs, we get –
= 124 ÷ 4 – 86 ÷ 2 + 61 + 17 × 3
= 31 – 43 + 61 + 17 × 3
= 31 – 43 + 61 + 51
= 100
So, 100 is the answer to the given equation. Hence, the first option is correct.
