Expected number of millionaires in Berlin based on ratio above:

Given:

The quadratic equation is

To find:

The vertex of the given quadratic equation.

Solution:

If a quadratic function is , then

We have,

It can be written as

          ...(i)

Here, .

Putting in (i), we get

On further simplification, we get

So, the vertex of the given quadratic equation is .

Therefore, the correct option is A.
