B. Vernisaj

Lui Petru ii este atrasa atentia de un grup de tineri galagiosi. Acestia discuta despre expozitia temporara de la muzeul de arta, promovata de afise publicitare in metrou. Unul spune: “Sunt cel putin 5 tablouri ale lui Grigorescu“. Cel de-al doilea il contrazice: ”Nu, sunt mai putin de 5 tablouri ale lui Grigorescu”. Apoi, un al treilea spune: ”Este cel putin un tablou al lui Grigorescu”. Daca unul singur dintre cei 3 tineri are dreptate, cate tablouri de Grigorescu sunt?

B. Exhibition

Peter's attention is drawn by a group of noisy young people. They discuss about the temporary exhibition at the art museum, promoted by advertisements in the underground. One says: "There are at least 5 paintings of Grigorescu." The second contradicts him: "No, there are less than 5 paintings of Grigorescu." Then a third one says: "It's at least one painting of Grigorescu." If only one of the three young people is right, how many paintings of Grigorescu are they?
