What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
15 ÷ 8 + 12 × 2 – 2 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 116.
Given equation: 15 ÷ 8 + 12 × 2 – 2 = ?
On interchanging the signs:
15 × 8 - 12 ÷ 2 + 2 = ?
? = 120 - 6 + 2
? = 122 - 6 = 116
