Question: Did the firm earn a positive profit in 2008 ?

(1) Firm XYZ had a profit 10% greater than its minimum profit over the period 2002-2007.

We do not know what was the minimum profit over the period 2002-2007. Even if we do, the knowledge would have no bearing on Profits of 2008. -Insuff

(2) Firm XYZ had a profit 20% lower than its median annual profit over the period 2002-2007.

The knowledge of profit for one year in between 2000 and 2007 has no bearing on Profits of 2008. -Insuff

combining 1 and 2 does not provide any relevant knowledge about year 2008, because no relation exists between the period 2002-2007 and year 2008. -Insuff

So, E
Smack is Back ...
It takes time and effort to explain, so if my comment helped you please press Thanks button :)

Agree, knowing information about 2002 - 2007 will never tell you about 2008 without additional information provided.Therefore the answer is E.
