Lets do it the other way around 0 at the end So 10 to leave fight 3 = you had 5$ when entering fight 3 cuz it dubbled. You had to pay 10 to get in and 5 left to dubble inside so you had 15 before entering fight 3 15+10 you needed to pay to leave fight 2 = 25 when inside fight 2 25/2 as you dubbled the money in fight 2 = 12.5 +10 to enter fight 2 = 22.5 before entering fight 2 10 to leave fight 1 = 32.5. But you need to half that once inside 32.5 = 16.25 16.25+10 because you need to pay to enter fight one = 26.25€ at the start

This aren't really brain teasers but jokes. As the awnsers of these "wally tests" are often illogical or well known jokes. *edit* yes i made a account just to say this. It was driving me insain that these were called Logic/Math Puzzles instead of jokes.
