What will come in the place of ‘?’ in the following equation if ‘+’ and ‘-’ are interchanged and ‘×’ and ‘÷’ are interchanged?
18 ÷ 9 + 24 × 3 - 16 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 170.
Given equation: 18 ÷ 9 + 24 × 3 - 16 = ?
On interchanging the signs:
(18 × 9) - (24 ÷ 3) + 16 = ?
? = 162 - 8 + 16
? = 178 - 8 = 170
