B Correct answer
Explanation

Initial mixture: 10 litres, 40% milk = 4 litres milk, 6 litres water. Add 6 litres milk: New milk = 4 + 6 = 10 litres. New total = 10 + 6 = 16 litres. Percentage = 10/16 = 62.5%.

AI explanation

The initial 10 litre mixture contains 40% milk, yielding 4 litres of milk. Adding 6 litres of pure milk brings the total milk to 10 litres and the total solution volume to 16 litres. Using the percentage formula (Part divided by Whole) times 100, the new percentage of milk is (10 divided by 16) times 100, resulting in 62.5%.
