What will come in place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
84 – 112 × 8 + 15 ÷ 3 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 53.
Given equation: 84 – 112 × 8 + 15 ÷ 3 = ?
On interchanging the signs:
84 + 112 ÷ 8 - 15 × 3 = ?
? = 84 + 14 - 45
? = 98 - 45 = 53
