If ‘+’ means ‘–’ , ‘–’ means ‘×’ , ‘×’ means ‘÷’, ‘÷’ means ‘+’, what will come in place of the question mark (?) in the following equation?
42 × 3 – 16 ÷ 9 + 11 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 222
After decoding, the new equation will be:
(42 ÷ 3) × 16 + 9 - 11 = ?
(14 × 16) + 9 - 11 = ?
(224 + 9) - 11 = ?
233 - 11 = ?
222 = ?
