One canned juice drink is 25% orange juice another is 5% orange juice. How many liters of each should be mixed together in order to get 20L that is 24% orange juice?
How many liters of the 25% orange juice should be in mixture?
How many liters of the 5% orange juice should be in mixture?
How can I solve this problem, or what is the best method??
Let V be the volume of the 25% orange juice.
Since the total volume is 20 l, the volume of 5% orange juice is (20-V).
The resulting mixture is 24%, therefore
25%*V + 5%*(20-V) = 24%*20
Can you solve for V? (It is a whole number close to 20).
