117. A company’s two divisions performed with remarkable consistency over the past three years: in each 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?

chemecials division.

pharmaceuticals division.
(D) The product mix offered by each of the company’s divisions has remained unchaged.
(E) Highly profitable products accounted for a higher percentage of the chemicals division’s
