What will come in the place of the question mark (?) in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged?
14 - 15 ÷ 2 + 56 × 14 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 40.
Given equation: 14 − 15 ÷ 2 + 56 × 14 = ?
On interchanging the signs:
14 + (15 × 2) - (56 ÷ 14) = ?
? = 14 + 30 - 4 = 40
