#1473

Cei n elevi de la grupa pregătitoare au primit câte două cartonaşe, fiecare cartonaş având scris pe el un număr natural. Ei s-au aşezat în cerc şi, la un semnal dat, fiecare a scos la întâmplare un cartonaş din buzunar. Copiii vă roagă să răspundeţi la următoarele întrebări:
1. Care poate fi suma maximă S a numerelor de pe cartonaşele scoase, ştiind că produsul acestora este divizibil cu un număr prim p?
2. Care poate fi lungimea maximă L a unei secvenţe de copii de pe cerc pentru care suma numerelor de pe cartonaşele oricăror doi vecini din secvenţă este pară?
