If '+' means '–', '–' means '÷', '÷' means '×' and '×' means '+', then what will come in place of the (?) in the following equation?
300 – 2 + 50 × 3 ÷ 2 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 106.
Given conditions: '+' means '–', '–' means '÷', '÷' means '×' and '×' means '+'
Given equation: 300 – 2 + 50 × 3 ÷ 2 =?
After interchanging the expression becomes:
= 300 ÷ 2 - 50 + 3 × 2
= 150 - 50 + 3 × 2
= 150 - 50 + 6 = 106
