Geometry Math Problem!?
there are 8 bags w/ the same weight but one bag, lets say bag 7, loses some gold but no one knows that. you have to weigh the bags only 2 times and come up with bag 7. I think it's 2 weighings but im not sure. i did it in 3 weighings by putting 4 bags on each scale then 2 bags then 1 bag and of course got bag 7.
