A mixture of milk and water is in the ratio 4:1, respectively. If 10 liters of the mixture are taken out, then the water becomes \(\tfrac{2}{3}\) of the milk. Find the initial quantity of water (in liters).
- 4
- 12
- 18
- 2
Correct answer: 2
Solution
Let the initial quantities be 4x liters of milk and x liters of water. After removing 10 liters from the mixture, the remaining quantities are proportional to the original ratio, and the condition that water becomes \(\tfrac{2}{3}\) of milk gives x = 2. Hence the initial water quantity is 2 liters.
