What will come in place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
60 × 12 − 6 ÷ 4 + 15 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 14.
Given equation: 60 × 12 − 6 ÷ 4 + 15 = ?
On interchanging the signs:
60 ÷ 12 + 6 × 4 - 15 = ?
? = 5 + 24 - 15
? = 29 - 15 = 14
