Answer 1

1250

Step-by-step explanation:

To know the size of the population, we will assume that the ratio is constant.

So, taking into account that 4 out of 50 deer has the mark and in total 100 deers have the mark, we can calculate the population as:

`(Mark)/(Total)=(4)/(50)=(100)/(x)`

Then, solving for x, we get:

`\begin{gathered} (4)/(50)=(100)/(x) \\ 4\cdot x=50\cdot100 \\ 4x=5000 \\ (4x)/(4)=(5000)/(4) \\ x=1250 \end{gathered}`

Therefore, there is a population of 1250 deers
