A Correct answer
Explanation

Initial: 16L, 5:3 ratio -> 10L milk, 6L water. Let x be milk added. (10+x)/6 = 2/1. 10+x = 12, so x = 2.

AI explanation

In the original 16 litre mixture, the amount of milk is 5/8 of 16, which is 10 litres, and the amount of water is 6 litres. Let x litres of milk be added to achieve a 2:1 ratio, making the equation (10 + x) / 6 = 2. Solving this equation gives 10 + x = 12, so x = 2. The amount of milk to be added is 2 litres.
