You are correct on what this puzzle is from. I am a geocacher and have been stumped on this puzzle for a while. Several puzzlers make logic puzzles.
The variables as I saw them are:
Frodo, Pippin, Bilbo, Sam, Merry, Rosie
Pilsner, Larger, Hefewran, Dark Ale, Porter, Stout Beer
Pitchers, Bottles, Pints, Humpens, Tanlards, Mugs
40, 45, 50, 55, 60, 65
Think $40 was out base number and we need six number the only option seems to be 65 without duplicating a number.
