What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
2 ÷ 90 × 5 – 4 + 10 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 30.
Given equation: 2 ÷ 90 × 5 – 4 + 10 = ?
On interchanging the signs:
2 × 90 ÷ 5 + 4 - 10 = ?
? = 36 + 4 - 10
? = 40 - 10 = 30
