I think @cuh posted this earlier, but the question was:
Circle A has 1/3 the radius of circle B. Circle A rolls around circle B until it returns to its starting position. How many revolutions of circle A are there in total?
Try the question for yourself before clicking on the videos. The correct answer is 4.
