I've put this post in the Just for Fun category, though those who hated math in school might not think so. I'm one of those weird folks who loved both mathematics and taking SAT-type tests. Admittedly, they aren't as much fun today as they used to be, ever since they took out the analogy and quantitative comparison questions. (A pity, since they replaced questions that test your general ability to think (scholastic aptitude) with ones more related to coursework (making it easier to "teach to the test").

Be that as it may, there's no test here, but a fascinating mathematical deep dive, at a layman's level, inspired by a question that everyone, including the test-makers, got wrong on a Scholastic Aptitude Test given back in 1982.
