None of the above
Incorrect AnswerExplanation:
- Mixture A has a water to milk ratio of 4:1. This means, in 250 liters, there are 200 liters of water and 50 liters of milk.
- Mixture B has 25 liters of water. The water to milk ratio is 5:7. Therefore, the milk in B is \(\frac{25 \times 7}{5}=35\) liters.
- When 40% of Mixture A is taken, it means \(0.4 \times 250 = 100\) liters are mixed, resulting in 80 liters of water and 20 liters of milk.
- 80% of Mixture B means \(0.8 \times 60 = 48\) liters are used. Thus, 20 liters of water and 28 liters of milk are mixed from B.
- Mixture C is being made combining the above mixtures, leading to 100 liters of water and 48 liters of milk.
- The ratio of milk to water in Mixture C is 48:100, which simplifies to 12:25.
