What will come in the place of the question mark ‘(?)’ in the following equation, if ‘−’ and ‘÷’ are interchanged and ‘×’ and ‘+’ are interchanged?
40 + 24 − 6 × 12 ÷ 3 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 169.
Given equation: 40 + 24 − 6 × 12 ÷ 3 = ?
After interchanging the sign:
40 × 24 ÷ 6 + 12 - 3 = ?
? = 160 + 12 - 3
? = 172 - 3 = 169
