What will come in place of the question mark (?) in the following equation if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
135 × 5 – 12 ÷ 11 + 8 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 151.
Given equation: 135 × 5 – 12 ÷ 11 + 8 = ?
On interchanging the signs:
135 ÷ 5 + 12 × 11 - 8 = ?
? = 27 + 132 - 8
? = 159 - 8 = 151
