What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
18 ÷ 5 + 8 × 4 − 3 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 91.
Given equation: 18 ÷ 5 + 8 × 4 − 3 = ?
On interchanging the signs:
18 × 5 - 8 ÷ 4 + 3 = ?
? = 90 - 2 + 3
? = 93 - 2 = 91
