In a huge park, people are concentrated at three points (see figure):



A: where there are different slides and swings for children,
B: near which a man-made lake is situated,
C: which is near to a large parking and exit. Where should an icecream parlour be set up so that maximum number of persons can approach it?

[Hint: The parlour should be equidistant from A, B and C.]
