A Correct answer
Explanation

Initial mixture: 80L milk, 20L water. After selling 1/4 (25L total), 75L remains (60L milk, 15L water). Adding 25L water results in 60L milk and 40L water. The ratio of water to milk is 40:60, which simplifies to 2:3.

AI explanation

The initial mixture of 80 litres of milk and 20 litres of water totals 100 litres, with water constituting one-fifth of it. When one-fourth of this mixture, or 25 litres, is sold, the remaining 75 litres contains 60 litres of milk and 15 litres of water. Adding 25 litres of water brings the water volume to 40 litres while the milk volume stays at 60 litres, making the current proportion of water to milk 40 to 60, which simplifies to 2 to 3.
