Question : Directions: If A denotes +, B denotes ×, C denotes −, and D denotes ÷, what will be in place of (?) in the following equation?
56 D 8 B 7 = (?) B 7
Option 1: 9
Option 2: 7
Option 3: 8
Option 4: 12
Correct Answer: 7
Solution :
Given:
A denotes +, B denotes ×, C denotes −, and D denotes ÷
56 D 8 B 7 = (?) B 7
After replacing the letters with the mathematical signs, we get:
⇒ 56 ÷ 8 × 7 = a × 7
⇒ 7 × 7 = a × 7
⇒ 49 = a × 7
⇒ a = 7
So, 7 is the answer to the given equation. Hence, the second option is correct.
