What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘÷’ are interchanged and ‘−’ and ‘×’ are interchanged?
4 − 6 × 27 ÷ 72 + 6 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 9.
Given equation: 4 − 6 × 27 ÷ 72 + 6 = ?
After interchanging the signs:
4 × 6 - 27 + 72 ÷ 6 = ?
? = 24 - 27 + 12
? = 36 - 27 = 9
