If I denotes ‘÷’, J denotes ‘×’, K denotes ‘-’, and L denotes ‘+’, then what will come in place of ‘?’ in the following equation? 

29 J 7 K 168 I 4 L 71 K 39 L 14 J 2 =?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 221.

Given conditions: I denotes ‘÷’, J denotes ‘×’, K denotes ‘-’, and L denotes ‘+’

Given equation: 29 J 7 K 168 I 4 L 71 K 39 L 14 J 2 = ?

After interchanging the expression becomes:

= (29 × 7) - (168 ÷ 4) + 71 - 39 + (14 × 2)

= 203 - 42 + 71 - 39 + 28

= 302 - 42 - 39

= 302 - 81

= 221

Hence, 221 is the correct answer.
