If ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’, then what will come in place of the question mark (?) in the following equation?
14 – 7 ÷ 42 × 6 + 33 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 72.
Given conditions: ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’
Given equation: 14 – 7 ÷ 42 × 6 + 33 =?
After interchanging the expression becomes:
= 14 × 7 + 42 ÷ 6 - 33
= 14 × 7 + 7 - 33
= 98 + 7 - 33
= 105 - 33
= 72
Hence, 72 is the correct answer.
