In a 40 L mixture, the ratio of milk to water is 5:3. How much water must be added to make the ratio 1:1?

1. 5 L
2. 8 L
3. 10 L
4. 12 L

Correct answer: 10 L

Solution

In 40 L, milk = \(40 \times \frac{5}{8} = 25\) L and water = \(40 \times \frac{3}{8} = 15\) L. To make the ratio 1:1, water must also be 25 L, so 10 L more water is needed.
