If I denotes ‘÷’, J denotes ‘×’, K denotes ‘−’ and L denotes ‘+’, then what will come in place of ‘?’ in the following equation?
118 L (16 I 4) K (72 J 2) L 28 L (39 J 3) = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 123.
Given equation: 118 L (16 I 4) K (72 J 2) L 28 L (39 J 3) = ?
After interchanging the expression becomes:
= 118 + (16 ÷ 4) - (72 × 2) + 28 + (39 × 3)
= 118 + 4 - 144 + 28 + 117 = 123
