because 50 and 100 sounds made up. its too round and too convenient. when people lie about numbers, they tend to go with odd numbers or numbers that are not nice and round.
’‘since i quit working for google i have purchased 100 cars with the money i earned’’
’‘since i quit working for google i have purchased 72 cars with the money i earned’’
what one sounds more believable to you?
