Five circles are arranged in the following fashion ( Two rows of 3 circles in square arrangement with one end circle removed from the top row ). Circles are of same diameter and touching adjoining circles as per the diagram. Draw a line passing through A ( Centre of the first circle on the bottom row ) in such a way that it divides the five circles into two equal areas.

solution by Stefan)
Stefan,
When I first glanced at your solution I didn't take it in, I was too concerned to see whether anyone had posted my viewpoint.
After having offered my response I note that we both had chosen a geometric construction.
I tend to feel that your solution is tidier than mine as it requires less constructional work to get to the result.
Well done.
