In a vessel, the ratio of water to milk is 3 : 7. 25% of the mixture is taken out from a total quantity of 200 liters and poured into another empty vessel, 10 liters of water is also added to this vessel. Find the total quantity of water in the second vessel.  
1. 18 liters
2. 20 liters
3. 31 liters
4. 28 liters
5. 25 liters

Answer 1

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.
