Question : Directions: If A denotes +, B denotes ×, C denotes −, and D denotes ÷, then what will be the value of the following expression?
90 C 20 B 1 A 36 D 2 = ?
Option 1: 88
Option 2: 38
Option 3: 78
Option 4: 86
Correct Answer: 88
Solution :
Given:
A denotes +, B denotes ×, C denotes −, and D denotes ÷
90 C 20 B 1 A 36 D 2 = ?
After replacing the letters with the mathematical signs, we get –
= 90 − 20 × 1 + 36 ÷ 2
= 90 − 20 × 1 + 18
= 90 − 20 + 18
= 88
So, 88 is the answer to the given equation. Hence, the first option is correct.
