What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
31 × 961 ÷ 155 – 73 + 54 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 24.
Given equation: 31 × 961 ÷ 155 – 73 + 54 = ?
On interchanging the sign:
31 ÷ 961 × 155 + 73 - 54 = ?
? = 5 + 73 - 54
? = 78 - 54 = 24
