Suppose she added x liters
First she has 0.2 pure fruit.
Make and equation based on pure fruit:
(2+x)/4=0.2+x
2+x=0.8+4x
1.2=3x
x=0.4 Liters pure fruit.

the composition is currently 200ml pure to 1800ml, let amount of pure too add=x
(0.2+x)/(2+x)=0.25
0.2+x=0.25*(2)+0.25x
.75x=.5-.2
x=0.4
therefore she must add 0.4 litres.
600/2400 is 25%
