What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘÷’ are interchanged and ‘×’ and ‘−’ are interchanged?
18 ÷ 6 + 2 − 3 × 4 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 23.
Given equation: 18 ÷ 6 + 2 − 3 × 4 = ?
After interchanging the signs:
18 + 6 ÷ 2 × 3 - 4 = ?
? = 18 + 9 - 4
? = 27 - 4 = 23
