B Correct answer
Explanation

Initial: 50L, ratio 3:2 (30L milk, 20L water). Remove 10L mixture (6L milk, 4L water). Remaining: 24L milk, 16L water. Add 12L each: 36L milk, 28L water. Ratio water:milk = 28:36 = 7:9.

AI explanation

A 50-litre mixture with a milk to water ratio of 3:2 contains 30 litres of milk and 20 litres of water. Removing 10 litres of this mixture removes 6 litres of milk and 4 litres of water, leaving 24 litres of milk and 16 litres of water. After adding 12 litres each of milk and water, the final mixture contains 36 litres of milk and 28 litres of water. The ratio of water to milk is therefore 28 to 36, which simplifies to 7:9.
