Correct Answer - Option 5 : 25 liters

**Given:**

Initial ratio = 3 : 7

Total quantity = 200 liters

Quantity removed = 25%

Water added = 10 liters

**Calculation:**

Quantity of water in first vessel = 200 × 3/10 = 60 liters

Quantity of water taken out = 25% of 60 = 15 liters

∴ Total quantity in second vessel = 15 + 10 = 25 liters

**∴ The answer is 25 liters.**
