What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
15 ÷ 15 – 30 + 225 × 25 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 246.
Given equation: 15 ÷ 15 – 30 + 225 × 25 = ?
On interchanging the signs:
15 × 15 + 30 - 225 ÷ 25 = ?
? = 225 + 30 - 9
? = 255 - 9 = 246
