Title: sup guys the NPR Weekend Edition puzzle was really easy today
Post by: Triarius Fidelis on June 29, 2008, 06:26:50 am
"From a 19th century trade card advertising Bassetts Horehound Troches, a remedy for coughs and colds: A man buys 20 pencils for 20 cents and gets three kinds of pencils in return. Some of the pencils cost 4 cents each, some are two for a penny and the rest are four for a penny. How many pencils of each type does the man get?"

Hints: Gauss, unique integer solution

The Weekend Edition problem is really the classic 'hundred fowls' problem in a different guise. Actually, scratch 'classic', it's 'exceedingly old'. This one's been around forever.

Here's how to solve it if you're really stuck.
