Assume that the two containers of alcohol concentration and B were 50 %, 100 % of the volume are exposed x liters , 20 liters of alcohol in the container out of higher alcohol 100 x% , but also in the alcohol x liters 50 % after concentration : u301450 % x + ( 20 -X ) 100 % u3015 / 2010 liters of alcohol containers outside liters x 50 % alcohol, but also in 100 % alcohol xl after concentration : u3014100 % x + (10 - x ) 50 % u3015 / 10 two equations equal tie x = 20/3 If the assumption of two containers of alcohol concentrations were 100% B , 50%, the conclusion is also true that , in 20 liters of alcohol / 3 liters
