What will come in place of the question mark (?) in the following equation if ‘+’ and ‘÷’ are interchanged and ‘×’ and ‘-’ are interchanged?
4 - 12 + 3 ÷ 12 × 6 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 22.
If '+' and '÷' are interchanged, and '×' and '-' are interchanged. We get;
4 × (12 ÷ 3) + 12 - 6 = ?
⇒ (4 × 4) + 12 - 6 = ?
⇒ (16 + 12) - 6 = ?
⇒ 28 - 6 = ?
⇒ 22 = ?
