You can put this solution on YOUR website!
Let = liters of 20% juice needed
Let = liters of 10% juice needed
given:
(1) liters of 12% mixture
OJ in 20% juice is liters
OJ in 10% juice is liters
OJ in 12% juice is liters
In words:
(liters OJ in 20% mix + liters OJ in 10% mix)/(total liters of 12% mix) = 12%

(2)
Subtract (1) from (2)
(2)
(1)
liters
and, since

liters
2 liters of the 20% juice and 8 liters of the 10%
juice need to be mixed
check answer:

OK
