Answer:
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%.
