Vsauce2 | The Missing Dollar Riddle @Vsauce2 | Uploaded 5 years ago | Updated 4 hours ago
Kevin explores the math and mystery behind a classic riddle that just… doesn’t make sense. Three friends go out to lunch and split a $30 bill evenly. Each pays ten bucks. Then the waitress realizes the bill should’ve been only $25.

She gives the busboy a $5 refund, but he can’t figure out how to evenly divide five dollars three ways. The customers don’t even know they’ve been overcharged, so he just takes a $2 tip for himself and hands the three customers one dollar each.

If the customers only paid $9 each for lunch and the busboy pocketed $2, where is the missing dollar?!?
