What will come in place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
56 – 14 × 7 ÷ 22 + 63 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 37.
Given equation: 56 – 14 × 7 ÷ 22 + 63 = ?
On interchanging the sign:
56 + 14 ÷ 7 × 22 - 63 = ?
? = 56 + 44 - 63
? = 100 - 63 = 37
