AI explanation

The 20-liter mixture has milk and water in a 5:3 ratio, meaning it contains 12.5 liters of milk and 7.5 liters of water. Removing 4 liters removes 2.5 liters of milk and 1.5 liters of water, leaving 10 liters of milk and 6 liters of water. Adding 4 liters of milk brings the final amounts to 14 liters of milk and 6 liters of water, giving a 7:3 ratio.
