In a 48 L mixture, the ratio of milk to water is $3:5$. How much water must be removed to make the ratio $1:1$?

1. 6 L
2. 9 L
3. 12 L
4. 15 L

Correct answer: 12 L

Solution

Total parts = $3+5=8$, so each part is $48/8=6$ L. Milk = $3\times 6=18$ L and water = $5\times 6=30$ L. For a $1:1$ ratio, water must also be 18 L, so 12 L water must be removed.
