If ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’, then what will come in place of the question mark (?) in the following equation?
124 × 4 ÷ 13 – 3 + 36 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 34.
Given conditions: ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’
Given equation: 124 × 4 ÷ 13 – 3 + 36 = ?
After interchanging the expression becomes:
= 124 ÷ 4 + 13 × 3 – 36
= 31 + 13 × 3 – 36
= 31 + 39 – 36
= 70 - 36 = 34
