|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:
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. :-)
