A mixture contains milk and water in the ratio 3:5. If the total quantity is 40 litres, how much milk should be added to make the ratio 1:1?

1. 8 L
2. 10 L
3. 12 L
4. 15 L

Correct answer: 10 L

Solution

The total mixture is 40 L in the ratio 3:5, so milk = 15 L and water = 25 L. To make the ratio 1:1, milk must also become 25 L, so 10 L milk must be added.
