What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
39 ÷ 3 – 24 + 60 × 12 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 136.
Given equation: 39 ÷ 3 – 24 + 60 × 12 = ?
On interchanging the signs:
39 × 3 + 24 - 60 ÷ 12 = ?
? = 117 + 24 - 5
? = 141 - 5 = 136
