Calculate number knowing how much is a percentage of it

Question

So, the question is, how to calculate the total number of players if I'm the 207th , placed 0.0167% of top.

Answer 1

It is a discrete uniform distribution on $\{1,\dots,n\}$ where $n$ is the total number of players. You have $\mathbb{P}[X\le 207]=0.0167\%$. You also have $\mathbb{P}[X\le k]=\frac{k}{n}$, so that you have $n\approx\frac{207}{0.0167\%}=1239520.95808$

Answer 2

Say there are $100x$ players.
Then according to your position,
$0.0167x=207 \Rightarrow 100x \approx 1239520$
