I'm dying a slow DS death

by Mclaughlin » Tue Jul 15, 2008 4:44 pm
I need help with strategy on this one! I can't seem to get any right and i've taken 5 manhattan GMAT practice tests and they always seem to re-write the problem in a way I just don't see and not sure I ever will see. Any strategy suggetions on how to attack these?
