Solution P is 20 percent lemonade and 80 percent carbonated water by volume; solution Q is 45 percent lemonade and 55 percent carbonated water by volume. If a mixture of PQ contains 72% percent carbonated water, what percent of the volume of the mixture is P?
Answer/Solution
68%
Steps/Work
72% is 8%-points below 80% and 17%-points above 55%.
So the ratio of solution P to solution Q is 17:8.
Mixture P is 17/25 = 68% of the volume of mixture PQ.
The answer is E.
So the ratio of solution P to solution Q is 17:8.
Mixture P is 17/25 = 68% of the volume of mixture PQ.
The answer is E.
