As per the forum rules, we need a verifiable source for the problem before we can deal with this question. If the question is not one of ours or one that is copyright-free, we will have to delete the question..

My biggest concern is that the exact wording of (1) indicates that l=42, but the GMAT would never indicate this in such a convoluted way..

unfortunately we can't give you any help on this question, because the question itself is flawed in a way that you won't see on the GMAT. please understand that using practice questions from dubious sources can actually hurt your performance, and be careful which problem sources you use..

Amy, did you read my post? This question is invalid; you should not be trying to solve it because it will only cause you trouble..
