What will come in place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
2 ÷ 8 − 25 × 5 + 9 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 12.
Given equation: 2 ÷ 8 − 25 × 5 + 9 = ?
After interchanging the signs:
2 × 8 + 25 ÷ 5 - 9 = ?
? = 16 + 5 - 9
? = 21 - 9 = 12
