What is the final percentage of a solution that is made from mixing 300ml of 70% alcohol with 200ml of 95% alcohol?

reply: (Keith) This is actually not an Alligation problem. You can use alligation to double check it when you are done, but figuring it out you should use C1V1 = C2V2.

For more examples of how to do this kind of problem, check out THIS PAGE. Here is what I get:

(300)(.70)+(200)(.95)= (500)(X)

210 + 190 = 500x

400     =    500x

----            ----

500             500

.80   =   X

Wouldn't it be 80% since they asked for percentage?
