 Difficult Logic Problems My version of Cheryl's Birthday problem
 Fri Feb 02, 2018 10:24 am  by josegarrido2 Hi, I would like to share with you a more difficult version of Cheryl's birthday problem, for those of you that found it easy. So the problem is as follow: Albert and Bernard just become [sic] friends with Cheryl, and they want to know when her birthday is. Cheryl gives them a list of possible dates: [img]https://doc-04-a0-docs.googleusercontent.spam/docs/securesc/ha0ro937gcuc7l7deffksulhg5h7mbp1/ioca1edmqbib7tg32f4b7ojj2a9vhf42/1517565600000/05728402239822500404/*/1KD6KBCyEGe7E8KeJGi9pszGiDEGvTOMO[/img] Then Cheryl tells Albert the month and Bernard the day. Albert: I Don't know when Cheryl's birthday is, and I also know that you know that I know that you don't know it. Bernard: Thanks for your information, but I don't know now either. Albert: Nor I do. Bernard: But now I do! Albert: So I do! So, when is cheryl's birhday? You will not deny that the statements sound pretty awesome. :-) Best regards, JosÃ© Antonio Garrido.
