What will come in the place of '?' in the following equation, if '×' and '÷' are interchanged?
18 - 2 + 12 × 4 ÷ 7 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 37.
Given equation: 18 - 2 + 12 × 4 ÷ 7 = ?
After interchanging the expression becomes:
= 18 - 2 + (12 ÷ 4) × 7
= 18 - 2 + (3 × 7)
= 18 - 2 + 21
= 39 - 2
= 37
