Twenty percent of a mixture of pure milk and water is water. Half a litre of the mixture of water and milk and throughly mixed. What percentage of the new mixture is water?

In the new mixture, the percentage of water with respect to its total is 13.33%.

Step-by-step explanation:

Given that in a liter of mixture 20% of it was water and the remaining 80% was pure milk, and that half a liter of wine was added to that liter of mixture, to determine the percentage of water in the new mixture is necessary to perform the following calculation:

20 + 80 + 50 = 150

150 = 100

20 = X

((20 x 100) / 150) = X

2,000 / 150 = X

13.33 = X

Thus, in the new mixture, the percentage of water with respect to its total is 13.33%.
