    Explanation:

    - Start with 60 liters of pure milk. Remove 10 liters, leaving 50 liters.

    - Add 25 liters of water, making the mixture 50 liters milk and 25 liters water.

    - 60% of this mixture is taken out, which is 45 liters (30 liters milk, 15 liters water).

    - 15 liters left, which includes 20 liters milk and 10 liters water.

    - Mix with another mixture (40 liters) containing 60% milk (24 liters) and 40% syrup (16 liters).

    - The combined mixture has 44 liters milk, 10 liters water, and 16 liters syrup.

    - Final ratio is 44:10:16, which simplifies to 22:5:8.
