What will come in the place of the question mark (?) in the following equation if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
12 × 3 – 5 ÷ 4 + 11 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 13.
Given equation: 12 × 3 – 5 ÷ 4 + 11 = ?
On interchanging the sign:
12 ÷ 3 + 5 × 4 - 11 = ?
? = 4 + 20 - 11
? = 24 - 11 = 13
