Given:

In a huge park, people are concentrated at three points.

To do:
We have to find where to set up an icecream parlour so that maximum number of persons can approach.

Solution:

Let us consider $ABC$ as a triangle.

Such that the three points in a triangle will be equidistant at circumcentre from the points $ABC$.

Therefore, let us join points $ABC$

Let us draw perpendicular bisectors to $AB$, $BC$ and $CA$

Now let mark the point of intersection as point $O$ this will be the circumcentre

Therefore, An ice cream parlour can be set up at $O$.
