Question: A pharmaceutical company received $5 million in royalties on the first $40 million in sales of and then $9 million in royalties on the next $210million in sales. By approximately what percentage did the ratio of royalties to sales decrease from the first $40 million in sales to the next $210 million in sales?
Options:
(A) 8%
(B) 15%
(C) 45%
(D) 52%
(E) 66% Let's think first. Some random reasoning:
(9/210)/(5/40) = 12/35 = 34% it means that 9/210 represents only 34%. Therefore a decrease of 66%. The final answer: (E).
