B Correct answer
Explanation

Let milk be 5x and water be x. After adding 5 liters of water, the ratio becomes 5x / (x + 5) = 5/2. Solving for x gives 2x = x + 5, so x = 5. The amount of milk is 5x = 25 liters.

AI explanation

Let the initial quantities of milk and water be 5x and x, respectively. After adding 5 litres of water, the equation becomes 5x / (x + 5) = 5 / 2, which simplifies to 10x = 5x + 25. Solving for x gives x = 5, so the amount of milk is 5 multiplied by 5, which is 25 litres.
