What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘ב are interchanged and ‘−’ and ‘÷’ are interchanged?
18 ÷ 6 + 5 × 14 − 7 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. -10.
Given equation: 18 ÷ 6 + 5 × 14 − 7 = ?
On interchanging the signs:
18 - 6 × 5 + 14 ÷ 7 = ?
? = 18 - 30 + 2
? = 20 - 30 = -10
