Question : Directions: If A denotes +, B denotes ×, C denotes –, and D denotes ÷, then what will come in place of (?) in the following equation?
2 B ? D 2 = 4 B 32 D 8
Option 1: 12
Option 2: 30
Option 3: 16
Option 4: 8
Correct Answer: 16
Solution :
Given:
2 B ? D 2 = 4 B 32 D 8
Let the missing number be a.
After replacing the letters with the mathematical signs, we get –
⇒ 2 × a ÷ 2 = 4 × 32 ÷ 8
⇒ 2 × a ÷ 2 = 4 × 4
⇒ 2 × a ÷ 2 = 16
⇒ a = 16
So, 16 is the answer to the given equation. Hence, the third option is correct.
