20% Alcohol in the 100 liter solution, 20 liters alcohol and 80 liters other solvents.
let, we add "x" liters of alcohol to the solution,
the new solution is "100+x" liters and alcohol, which was 20 liters, becomes 20+x liters.
so,
20+x = 25% of (100+x)
or,20+x=(100+x)/4
or,80+4x=100+x
or,3x=20
or,x=20/3
