C___x+2______0.25__________.25(x+2)=x+.2

so

.25 x + .5 = x+.2

.3 = .75 x

x = .3/.75 = .4 liters

1. 10%of 2 liters is .2 liters of pure fruit juice then,

To make it 25% we must add how much which is .3 liters to 2 liters which will make it 2.3 liters so 25% of 2.3 liters of juice will be 25/100 into 2.3 which is 1/4 into 2300 which is 23 into 25 milliliters

Which is .5 l approx
