Straight E, though a little bit tricky. All we need to know is the rates of these machines. Though from both statement the rates can be:
250 copies per minute and 500 copies per minute;
250 copies per minute and 125 copies per minute.

P.S. Please post PS questions in the PS subforum: gmat-problem-solving-ps-140/ and DS questions in the DS subforum: gmat-data-sufficiency-ds-141/
