What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
16 ÷ 4 + 18 − 14 × 7 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 48.
Given equation: 16 ÷ 4 + 18 − 14 × 7 = ?
On interchanging the signs:
16 × 4 - 18 + 14 ÷ 7 = ?
? = 64 - 18 + 2
? = 66 - 18 = 48
