If ‘I’ stands for ‘×’, ‘J’ stands for ‘+’, ‘K’ stands for ‘÷’ and ‘L’ stands for ‘−’, what will come in place of the question mark (?) in the following equation?
(40 J 32 K 4) I 5 L 155 J 7 I 9 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 148.
(40 J 32 K 4) I 5 L 155 J 7 I 9 = ?
Replacing letters with the signs in the expression:
= (40 + 32 ÷ 4) × 5 - 155 + 7 × 9
= 48 × 5 - 155 + 63
= 240 - 92
= 148
Hence, the correct answer is 148.
