What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
24 × 576 ÷ 72 – 108 + 91 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 20.
Given equation: 24 × 576 ÷ 72 – 108 + 91 = ?
On interchanging the sign:
24 ÷ 576 × 72 + 108 - 91 = ?
? = 3 + 108 - 91
? = 111 - 91 = 20
