Solution A is made up of alcohol and water mixed in the ratio of 21:4 by volume; Solution B is made up of alcohol and water mixed in the ratio of 2:3 by volume. If Solution A and Solution B are mixed in the ratio of 5:6 by volume, what percent of the resultant mixture is alcohol? Select:
A) 32.5%  B) 40%  C) 60%  D) 65%  E) Cannot be determined
let mixture after mixing A and B is 110 ml (number assumed for calculation because of 5:6)   now solution A is 50 ml and solu B is 60 ml   further in A 100 ml A contains 84 ml alch   so 50 ml contain 42 ml   in mix B 100 ml solution contain 40 ml alc , 60 ml of B , it will be 24 ml alcohol.   so 42+24=

<output>66</output>
66 in 110 ml solution which is 60%   ANSWER:60%
