What will come in the place of the question mark (?) in the following equation if ‘–’ and ‘×’ are interchanged and ‘÷’ and ‘+’ are interchanged?
6 − 8 ÷ 12 + 3 × 9 + 3 ÷ 17 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 66.
Given equation: 6 − 8 ÷ 12 + 3 × 9 + 3 ÷ 17 = ?
On interchanging the signs:
6 × 8 + 12 ÷ 3 - 9 ÷ 3 + 17 = ?
? = 48 + 4 - 3 + 17
? = 69 - 3 = 66
