A mixture contains 70% milk. If 40 liters of water is added to the 100-liter mixture, what is the new percentage of milk?

1. 50%
2. 45%
3. 55%
4. 60%

Correct answer: 50%

Solution

Initially, milk = 70% of 100 L = 70 L. After adding 40 L water, total mixture = 140 L while milk remains 70 L. So the new percentage of milk is \(\frac{70}{140}\times 100 = 50\%\).
