A Correct answer
Explanation

Initial: 60L, 3:2 ratio -> 36L milk, 24L water. Remove 20L: 12L milk, 8L water removed. Remaining: 24L milk, 16L water. Add 32L water: 24L milk, 16+32=48L water. Ratio 24:48 = 1:2.

AI explanation

The initial 60 litres contains milk and water in a 3 to 2 ratio, meaning there are 36 litres of milk and 24 litres of water. Removing 20 litres of the mixture removes one-third of each component, leaving 24 litres of milk and 16 litres of water. Adding 32 litres of water to the remaining mixture increases the water volume to 48 litres, resulting in a final ratio of milk to water of 24 to 48, which simplifies to 1:2.
