Buna seara,

Daca stiti cum se fac aceste probleme, va rog mult de tot.

1. Din 52 de numere naturale distincte putem alege doua a caror suma sau diferenta sa fie divizibila cu 100. Mai ramane aceasta afirmatie adevarata pentru 51 de numere naturale?

2. Daca 70 de numere naturale nenule distincte nu depasesc 200, atunci doua dintre ele au diferenta 4,5 sau 9.

Va multumesc mult de tot.
