It appears there is confusion rampant with this question.
It asks how large is the database. The question does *NOT* say anything about what are the total sizes of the files created.
Since the .mdf file is essentially the "database" and the .ldf file is the transaction log, this question is poorly worded, badly formed and subject to existing sizes in the model database - which is well beyond the scope (or probably the intention) of the question.
The version issues (SQL 2000/2005/2008) notwithstanding, this is just someone trying to be cute, not ask a meaningful question.
I love the questions that make me think or teach me something - neither of these attributes were present in this question.
Sorry to be harsh, but questions like this should not be posted.
