Here's a different "weighing problem", stolen from a "Columbo" from
years gone by...

You are given, say, 100 bags of 100 coins each; one of the bags contains
counterfeit coins, which weigh, say, 10% less than the real coins.
You must determine, in ONE weighing, which bag contains the counterfeits.

I'll post the solution in one week.
