I don't think anyone will have trouble doing this problem, but I wrote a solution anyway.
There are 5 coins placed flat on a table according to the figure. What is the order of the coins from top to bottom.
From looking at this picture, you can easily tell that coin C is the coin at the very top because it overlaps coins D, E, and A, and coins A and D are overlapping coin B. Coin D is overlapping coin A and B and overlapped by coin E. That makes coin E the second in the order of top to bottom and coin D the third. Because coin A overlaps coin B, coin A is going to be the 4th and coin B is the 5th. Therefore the order is (C,E,D,A,B).
