Reproduced here are various Mathematical Puzzles from
The Old Farmer's Almanac,
published continuously since 1792. All copyrights hereby acknowledged.
As mentioned in an earlier post,
a while back I bought a box full of vintage Old Farmer's Almanacs (OFA)
at a yard sale, figuring there would be a bunch of good items to post here on
RF Cafe and on my
Airplanes and Rockets hobby website. Chief
amongst the postworthy features is the Mathematical Puzzles section. They are a
fair challenge to an engineer's cerebration, contemplation, and deliberation. These
particular mathematical posers appeared in the 1974 issue of OFA. #10,
while rated a difficulty of 4 (where 5 is most difficult), is really not even a mathematical challenge when you think about it (hint - it's an old
riddle you've probably seen before). Enjoy!
Old and New Mathematical Puzzles
Blanton C. Wiggin, Editor
Last year, a number of excellent answers made judging very difficult. So we are
proud to announce the 1973 winner: Richard Stegner, Deerfield, Illinois. We made
a special exception and awarded two ad hoc second prizes to: Richard L. Collier,
Guilderland, New York; and Melzer Smith, Cutler, Maine.
For 1974, we have selected from a large number of fine entries the following
fifteen puzzles, arranged in an easy-to-hard order. No calculus or "higher math"
needed. We will award one prize of $15 for the best set of solutions to puzzles
No. 12 through No. 15 received before April 1, 1974. The answers for these four
puzzles are therefore omitted here. After April 1, 1974, however, we will send the
answers to these four, together with a discussion of the other answers, to anyone
sending a . stamped, self-addressed envelope to "Puzzle Answers." Yankee, Inc.,
Dublin, N .R. 03444. Our usual $5 offer holds for any original puzzle we use in
The 1975 Old Farmer's Almanac. Closing date for these submissions is also April
1, 1974. Entries become the property of Yankee, Inc., and cannot be acknowledged
or returned. Editor will choose among duplicates.
