What will come in the place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
14 ÷ 3 − 18 × 6 + 28 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 17.
Given equation: 14 ÷ 3 − 18 × 6 + 28 = ?
On interchanging the signs:
14 × 3 + 18 ÷ 6 - 28 = ?
? = 42 + 3 - 28
? = 45 - 28 = 17
