Sir , can you please suggest some name for the problem I mentioned above so that I can get some idea and I can try to give names that are meaningful from next time.

I was reading the wiki On AM - GM Inequality .In it I found out that there was a proof which said that it requires a bit of combinatorics . In the last bit of the proof , it said

$k > m_g > 0 \Rightarrow m_g \in {(0 , k)}$

$k \geq m_a > 0 \Rightarrow m_a \in {(0 , k]}$.

From these how does it follow that $m_a \geq m_g$ ?

@Calvin Lin Sir , recently I posted two questions ..the problem name changed automatically.

Like I named the problem 'Strange' , it changed to 'A geometry problem by Ankit Kumar Jain.

@Pi Han Goh Can you please help me out?

I don't know what $k, m_a$ and $m_g$ represents. So I can't help you with that...

$m_a$ is the arithmetic mean and $m_g$ is geometric mean and $k$ is some constant.

AM-GM .In the proof that says 'It requires a bit of combinatorics' , that one.
