What will come in the place of the question mark ‘(?)’ in the following equation, if ‘−’ and ‘÷’ are interchanged and ‘×’ and ‘+’ are interchanged?
32 + 49 − 7 × 4 ÷ 3 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 225.
Given equation: 32 + 49 − 7 × 4 ÷ 3 = ?
After interchanging the sign:
32 × 49 ÷ 7 + 4 - 3 = ?
? = 224 + 4 - 3
? = 228 - 3 = 225
