Lost Ring Puzzle: Weigh three parcels against another three parcels. If one side is heavier than the other, then one of those three parcels must contain the ring. If the two sides are equal, then the ring must be in one of the three parcels that were not weighed. From the group of three with the ring, weigh two of the parcels. If one side is heavier it has the ring. If they are equal, then the un-weighed parcel must have the ring.
