What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
25 + 20 × 10 ÷ 2 − 5 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 26.
Given equation: 25 + 20 × 10 ÷ 2 − 5 = ?
On interchanging the sign:
25 - 20 ÷ 10 × 2 + 5 = ?
? = 25 - 4 + 5
? = 30 - 4 = 26
