Correct Answer: 9
Solution : Given: [{(32 × 20) – (2 ÷ 3)} + (2 – 4)] ÷ 3 = ?
On interchanging the signs given in the equation, the equation becomes – = [{(32 – 20) + (2 × 3)} ÷ (2 + 4)] × 3 = [{12 + 6} ÷ 6] × 3 = [18 ÷ 6] × 3 = 3 × 3 = 9
So, 9 is the required answer to the given equation. Hence, the third option is correct.
