Question

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

Answer 1

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

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%.
