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