But kpadma dragged me into this. I think it is all about addiction. I wanr everyone about this addiction and suggest concentrating on certain known weak points.

Well, What can I say. I'm an addict, now!

Here is another method!

Customer gets 1 liter for $8

Vender pays (1-x)*$6.4 for that adulterated 1 liter milk and makes

37.5% profit.

Where X = water in 1 liter adulterated milk

6.4(1-x) * 1.375 = 8

Solve for X, we get 1/11.

Pure milk in 1 liter adultrated milk is 10/11

W:M = 1/11 : 10/11 = 1:10

Well, time for another round
