A flowerbed is decorated with four concentric circles of flowers, in such a way that each circle contains twice as many flowers as the cirde immediately inside, and the botal number of flowers The smallest square of the number of flowers placed on equals the arde. It is then true that (A) The number of flowers placed on the smallest arde is 16 of flowers on the two internal circles is 85. (B) The sum (c) The number of flowers placed on the greatest circle is (OD. (D) The e difference between the number and the smallest airde is 105. (E) The total of flowers on the greatest • number of flowers on the flowerbed is 144.
