What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
4 ÷ 8 × 2 − 7 +3 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 20.
Given equation: 4 ÷ 8 × 2 − 7 + 3 = ?

4 × 8 ÷ 2 + 7 - 3 = ?
? = 16 + 7 - 3
? = 23 - 3 = 20
