Question

One canned juice drink is 20​% orange​ juice; another is 55​% orange juice. How many liters of each should be mixed together in order to get 15L that is 88​% orange​ juice?

Answer 1

The answer is that it is not possible to increase the percentage beyond 55℅

even if you add 1L 22℅ to 1L 55℅ the answer would lie between the two numbers, but never exceed 55℅
