Thread about an unsolvable riddle? August 20, 2014 10:29 AM Subscribe
I can't seem to locate a thread I read here once about an impossible riddle or logic puzzle. I don't recall the riddle itself except that it was math-related, and the answers were multiple choice series of percentages: 50%, 25%, 10%, etc. The ensuing metafilter meltdown over the answer was highly entertaining, but I foolishly didn't mark it as a favorite, and now my searches are coming up empty. Can anyone help?
