Problema de logica
Pe urmele blogului lui Sorin, iaca ce se preumbla in ultima vreme pe net in materie de probleme de logica.
\Albert and Bernard just met Cheryl. “When’s your birthday?” Albert asked Cheryl. Cheryl thought a second and said, “I’m not going to tell you, but I’ll give you some clues.” She wrote down a list of 10 dates: May 15 — May 16 — May 19 June 17 — June 18 July 14 — July 16 August 14 — August 15 — August 17 “My birthday is one of these,” she said. Then Cheryl whispered in Albert’s ear the month — and only the month — of her birthday. To Bernard, she whispered the day, and only the day. “Can you figure it out now?” she asked Albert. Albert: I don’t know when your birthday is, but I know Bernard doesn’t know, either. Bernard: I didn’t know originally, but now I do. Albert: Well, now I know, too! When is Cheryl’s birthday? Eu am gasit raspunsul, cred Voi ? |

ramane iulie si august
bernard stie data asa ca trebuie sa fie una din 15 16 17 ... fiindca a zis ca stie deja data nasterii !!!
iar daca Albert stie luna si mai stie ca bernard deja cunoscand ziua si-a dat seama (deci nu purea fi august fiindca acolo e 15 17 ... deci e 16 iulie)
raspuns final 16 iulie !!!
