It's not ber hirthday anymore
Better late than never?
Suzan, Melvin and Florence are 3 friends. Melvin and Florence want to know Suzan’s birthday, so Suzan gives them 15 possible choices:
March: 3, 4, 7
April: 3, 5, 8
June: 3, 6
July: 4, 6, 8
August: 3, 8
Suzan then privately tells Melvin the month of her birth and privately tells Florence the day of her birth.
Melvin: I don’t know Suzan’s birthday, but I know that Florence definitely doesn’t know either.
Florence: At first I didn’t know, but after thinking about Melvin’s comment carefully I now know Suzan’s birthday!
Melvin: Well in that case I finally know Suzan’s birthday as well!
What is Suzan’s birthday?
