What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
66 × 6 − 15 ÷ 3 + 9 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 47.
Given equation: 66 × 6 − 15 ÷ 3 + 9 = ?
On interchanging the signs:
66 ÷ 6 + 15 × 3 - 9 = ?
? = 11 + 45 - 9
? = 56 - 9 = 47
