题目：A company's two divisions performed with remarkable consistency over the past three years:in each of those years, the pharmaceuticals divison has accounted for roughly 20 percent of those years, the pharmaceuticals division has accounted for roughly 20 percent of dollar sales and 40 percent of profits, and the chemicals division for the balance.
which of the following can properly be inferred regarding the past three years from the statement above?
A.total dollar sales for each of the company's divisions have remained roughly constant
B.the pharmaceuticals division has faced stiffer competition in its markets than has the chemicals division.
c.the chemicals division has realized lower profits per dollar of sales than has the pharmaceuticals division
d.the product mix offered by each of the company's divisons has remained unchanged.
e.highly profitable products accounted for a higher percentge of the chemicals division's sales than of those of the pharmaceuticals divisions.
这题的答案选C，OG上这样解释，the pharmaceuticals divison made 40 percent of the profits on only 20 percents of the sales, while the chemicals division,making up the balance, made 60 percent of the profits on 80 percent of the sales. thus, the chemicals divison made a lower profit per dollar of sale than the pharmaceuticals division, as choice asserts. choice is the best answers.
