What will came in the place of the question mark (?) in the following equation, if '+' and '÷' are interchanged and '×' and '-' are interchanged?
5 - 63 + 9 ÷ 10 × 6 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 39.
Given equation: 5 - 63 + 9 ÷ 10 × 6 = ?
After interchanging the signs:
5 × (63 ÷ 9) + 10 - 6 = ?
= (5 × 7) + 10 - 6
= (35 + 10) - 6
= 45 - 6
= 39
