What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
69 − 36 × 6 ÷ 12 + 5 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 136.
Given equation: 69 − 36 × 6 ÷ 12 + 5 = ?
On interchanging the signs:
69 + 36 ÷ 6 × 12 - 5 = ?
? = 69 + 72 - 5
? = 141 - 5 = 136
