I have this question that has me baffled.
A Fly crawls around the outside of a circle once. A second fly crawls around the outside of a square once. Which fly travels further?
1) The diagonal of the square is equal to the diameter of the circle.
2) The fly crawling around the circle took more time to complete his journey than the fly crawling around the square.
i think total distance around the circle and square can be compared easily..
i.e. perimeter of circle and perimeter of square. so A is suff. while no info is available about distance in B so isuff.
