What will come in the place of the question mark ‘(?)’ in the following equation, if ‘−’ and ‘÷’ are interchanged and ‘×’ and ‘+’ are interchanged?
9 + 56 − 8 × 4 ÷ 9 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 58.
Given equation: 9 + 56 − 8 × 4 ÷ 9 = ?
After interchanging the sign:
9 × 56 ÷ 8 + 4 - 9 = ?
? = 63 + 4 - 9
? = 67 - 9 = 58
