Question : Directions: If I denotes ÷, J denotes ×, K denotes –, and L denotes +, then what will come in place of (?) in the following equation?
17 J 6 K 21 L 93 I 3 L 35 K 12 = ?
Option 1: 135
Option 2: 130
Option 3: 140
Option 4: 128
Correct Answer: 135
Solution :
Given:
17 J 6 K 21 L 93 I 3 L 35 K 12 = ?
After replacing the letters with the mathematical signs, we get –
= 17 × 6 – 21 + 93 ÷ 3 + 35 – 12
= 17 × 6 – 21 + 31 + 35 – 12
= 102 – 21 + 31 + 35 – 12
= 135
So, 135 is the answer to the given equation. Hence, the first option is correct.
