- PROBLEM SOLVING IN MATHEMATICS -
**PsyDAG**, Saturday, October 1, 2011 at 7:50pmTry to get a "bit" (binary digit) of information with each weighing. This divides the possibilities as close as possible in half.

Start by weighing 6 bags at a time. If they both weigh the same, then the remaining bag is the fake. If not, divide the lighter set in half and weigh again. From this weighing, take the lighter set and weigh 2 and 1. If the one is not fake, then you only have one more weighing to go.

At the max, how many weighings is that?
