Express Rs 25 as percentage of Rs 75.

Reason:

1. Let x be the required percentage. Then 25 = (x/100) × 75.

2. Simplify the right side: (x/100) × 75 = (75x)/100 = (3x)/4.

3. So 25 = (3x)/4. Multiply both sides by 4 to get 100 = 3x.

4. Divide by 3: x = 100/3 = 33.333...%

Answer: 33.33% (approximately 33 1/3%)
