What will come in place of the question mark (?) in the following equation if ‘+’ and ‘×’ are interchanged and ‘−’ and ‘÷’ are interchanged?
14 ÷ 12 − 2 + 2 × 16 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 18.
Given equation: 14 ÷ 12 − 2 + 2 × 16 = ?
On interchanging the signs:
14 - 12 ÷ 2 × 2 + 16 = ?
? = 14 - 12 + 16
? = 30 - 12 = 18
