What will come in the place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
60 + 9 ÷ 63 − 72 × 12 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. -501.
60 + 9 ÷ 63 − 72 × 12 = ?
After interchanging the signs
60 - 9 × 63 + (72 ÷ 12) = ?
60 - (9 × 63) + 6 = ?
60 - 567 + 6 = ?
66 - 567 = ?
-501 = ?
