What will come in the place of the question mark ‘(?)’ in the following equation, if ‘−’ and ‘÷’ are interchanged and ‘×’ and ‘+’ are interchanged?
7 + 45 − 15 × 5 ÷ 12 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 14.
Given equation: 7 + 45 − 15 × 5 ÷ 12 = ?
On interchanging the signs:
7 × 45 ÷ 15 + 5 - 12 = ?
? = 21 + 5 - 12
? = 26 - 12 = 14
