On the shelf you have 10 identical bottles of identical pills (let?s say there?s a hundred pills in each bottle). However, one of those 10 bottles contains cheap knockoff pills. The only way to differentiate fake pills from real pills is the weight - while real pills weigh 1 g each, the knockoff pills are only 0.9 g. You have one scale that shows the exact weight (down to the mg) of whatever is weighed. How can you tell which bottle contains fake pills with just 1 weighing?

A, B and C are three points on a straight line, not necessarily equidistant with B being between A and C. Three semicircles are drawn on the same side of the line with AB, BC and AC as the diameters.
