Question : Directions: If I denotes ÷, J denotes ×, K denotes –, and L denotes +, then what will come in place of (?) in the following equation?
448 I 8 L 17 K 12 J 6 L 19 = ?
Option 1: 14
Option 2: 20
Option 3: 16
Option 4: 18
Correct Answer: 20
Solution :
Given:
448 I 8 L 17 K 12 J 6 L 19 = ?
After replacing the letters with the mathematical signs, we get:
⇒ 448 ÷ 8 + 17 – 12 × 6 + 19
⇒ 56 + 17 – 12 × 6 + 19
⇒ 56 + 17 – 72 + 19
⇒ 92 – 72
⇒ 20
So, 20 is the answer to the given equation. Hence, the second option is correct.
