A 20 L mixture contains milk and water in the ratio 2:3. How much milk must be added to make the ratio 4:3?

1. 10 L
2. 8 L
3. 5 L
4. 9 L

Correct answer: 8 L

Solution

In 20 L with ratio 2:3, milk = 8 L and water = 12 L. If x L milk is added, then \((8+x):12 = 4:3\), so \(3(8+x)=48\), giving \(x=8\) L.
