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.

1. obviously INSUFF since you know nothing about the other machine.
2. INSUFF since you dont know the rate - it could be 10/min or 20/min so end result differs
Combine:
M1 = 250/min
M2 COULD be 500/min OR 125/min since M1 could be the machine that produces 250/min AND the same machine that is twice the rate from 2. so as you can see the end result differrs.
