Q. If + means x, x means -, ÷ means + and – means ÷, then 175 – 25 ÷ 5 + 20 x 3 + 10 equals to:

Correct Answer: c) 77

Explanation:
– Replace each symbol by its given meaning:
+ means ×, x means −, ÷ means +, and − means ÷.
– So, 175 – 25 ÷ 5 + 20 x 3 + 10 becomes:
175 ÷ 25 + 5 × 20 − 3 × 10
– Apply BODMAS/PEMDAS:
175 ÷ 25 = 7
5 × 20 = 100
3 × 10 = 30
– Now compute: 7 + 100 − 30 = 77

Therefore, the value is 77.
