- ANSWER : 16 litres
SOLUTION :
Let total solution be x.
At first solution contain A = 0.8x & B = 0.2x
10 litre replacement means we remove 8 litre A and 2 litre B with 10 litres of B
So equation is
(0.8x-8)/(0.2x+8) = 2/3
Or, x = 20
so 20 litre solution contain 16 litre A and 4 litre B. - 12 years agoHelpfull: Yes(5) No(3)
