What will come in the place of the question mark ‘(?)’ in the following equation, if ‘÷’ and ‘×’ are interchanged and ‘+’ and ‘−’ are interchanged?
11 − 9 ÷ 2 + 16 × 8 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 27.
Given equation: 11 − 9 ÷ 2 + 16 × 8 = ?
After interchanging the sign:
11 + 9 × 2 - 16 ÷ 8 = ?
? = 11 + 18 - 2
? = 29 - 2 = 27
