Correct Answer: 20
Solution : Given: × stands for ÷, ÷ stands for +, + stands for –, – stands for × (30 + 20) – 5(7 ÷ 3) × 25 = ?
On replacing the mathematical signs according to the instructions given, we get – = (30 – 20) × 5(7 + 3) ÷ 25 = 10 × 5(10) ÷ 25 = 10 × 50 ÷ 25 = 10 × 2 = 20
Therefore, the required answer is 20. Hence, the third option is correct.
