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) =?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 55.
Given conditions: I denotes ‘÷’, J denotes ‘×’, K denotes ‘−’ and L denotes ‘+’
Given equation: (35 I 5) J 9 K 23 L 39 K (3 J 8) =?
After interchanging the expression becomes:
= (35 ÷ 5) × 9 - 23 + 39 - (3 × 8)
= 7 × 9 - 23 + 39 - 24
= 63 - 23 + 39 - 24 = 55
