The proportion of water to alcohol in Solution A is 5:4 and the proportion of water to alcohol in Solution B is 6:5. If an equal amount of each solution is mixed together, what is the concentration of alcohol in the new solution? Choose the correct choice from the following options
A) 40.9%
B) 41.9%
C) 42.9%
D) 43.9%
E) 44.9%
Let V be the total volume of the new solution.   Then a volume of V/2 was added from each solution A and B.   The amount of alcohol added to the new solution was:   (4/9)(V/2)+(5/11)(V/2)=2V/9+5V/22=89V/198.   The concentration of alcohol is 89/198=44.9%   The answer is 44.9%.
