What will come in place of the question mark (?) in the following equation if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
24 ÷ 6 + 18 × 9 – 2 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 144.
Given equation: 24 ÷ 6 + 18 × 9 – 2 = ?
On interchanging the sign:
24 × 6 - 18 ÷ 9 + 2 = ?
? = 144 - 2 + 2
? = 146 - 2 = 144
