What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
16 ÷ 8 + 13 + 36 × 18 − 3 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 116.
Given equation: 16 ÷ 8 + 13 + 36 × 18 − 3 = ?
On interchanging the signs:
16 × 8 - 13 - 36 ÷ 18 + 3 = ?
? = 128 - 13 - 2 + 3
? = 131 - 15 = 116
