Question : Directions: If I denotes ÷, J denotes ×, K denotes − and L denotes +, then what will come in place of (?) in the following equation?
(35 I 5) J 9 K 23 L 39 K (3 J 8) = ?
Option 1: 60
Option 2: 59
Option 3: 51
Option 4: 55
Correct Answer: 55
Solution :
Given:
I denotes ÷, J denotes ×, K denotes −, and L denotes +
(35 I 5) J 9 K 23 L 39 K (3 J 8) = ?
After replacing the letters with the mathematical signs, we get:
= (35 ÷ 5) × 9 – 23 + 39 – (3 × 8)
= 7 × 9 – 23 + 39 – 24
= 63 – 23 + 39 – 24
= 55
So, 55 is the answer to the given equation. Hence, the fourth option is correct.
