What will come in the place of the question mark ‘(?)’ in the following equation, if ‘÷’ and ‘×’ are interchanged and ‘+’ and ‘−’ are interchanged?
45 − 2 ÷ 8 + 2 × 2 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 60.
Given equation: 45 − 2 ÷ 8 + 2 × 2 = ?
After interchanging the sign:
45 + 2 × 8 - 2 ÷ 2 = ?
? = 45 + 16 - 1
? = 61 - 1 = 60
