Answer 2

$\it Fie\ \ a,\ \ b\ \ cele\ \ dou\breve a\ \ numere.\\ \\ a>b\ \ de\ \ 3\ \ ori \Rightarrow a=3b\ \ \ \ \ \ (1)\\ \\ m_a=\dfrac{a+b}{2}=1004\ \stackrel{(1)}{\Longrightarrow} \dfrac{3b+b}{2}=1004 \Rightarrow \dfrac{4b}{2}=1004\Rightarrow 2b=1004\Rightarrow \\ \\ \\ \Rightarrow b=1004:2 \Rightarrow b=502\ \ \ \ \ \ (2)\\ \\ \\ (1),\ (2) \Rightarrow a=3\cdot502$
