A container holding 12 ounces of a solution that is 1 part alcohol to 2 parts water is added to a container holding 9 ounces of a solution that is 1 part alcohol to 2 parts water. What is the ratio of alcohol to water in the resulting solution?  Choose the correct choice
A) 1:2
B) 3:7
C) 3: 5
D) 4:7
E) 7:3
Container 1 has 12 ounces in the ratio 1:2   or,   x+2x=12 gives x(alcohol)=4 and remaining water =8   container 2 has 9 ounces in the ratio 1:2   or,   x+2x=9 gives x(alcohol)=3 and remaining water =6   mixing both we have alcohol=4+3 and water =8+6   ratio thus alcohol/water =7/14=1/2   1:2nswer 1:2
