Answer:
the percentage of water in the mixture is 14%.
Step-by-step explanation:
1. Calculate the total amount of water in the first milk:
- Water in 90 liters of 10% water milk = 90 * 0.10 = 9 liters of water
2. Calculate the total amount of water in the second milk:
- Water in 60 liters of 20% water milk = 60 * 0.20 = 12 liters of water
3. Calculate the total amount of milk in the mixture:
- Total milk = 90 liters + 60 liters = 150 liters
4. Calculate the total amount of water in the mixture:
- Total water = 9 liters + 12 liters = 21 liters
5. Calculate the percentage of water in the mixture:
- Percentage of water = (Total water / Total milk) * 100
- Percentage of water = (21 / 150) * 100
- Percentage of water = 14%
