jason,

welcome to the forum, but ...

i noticed that you posted twelve different threads in 45 minutes, and that NONE of them conform to our forum rules at all. also, many (if not most) of the problems you've posted are nonsense, like this one -- it asks for "k", but there is no "k" mentioned in the problem at all.

therefore, i've deleted your posts, and i'd like to request that you do the following:

* READ THE FORUM RULES. (this is the first thread in every folder.)
note in particular how to title your posts -- you can't just use titles like "a math problem". read the forum rules for the correct way to write post titles.

* SEARCH THE FORUM for existing threads on these problems -- if the problem is from GMAT PREP, then the chance that it has already been posted and discussed is very close to 100%.

* if you find existing threads, then post your questions on those threads.
do not start new threads unless you are reasonably sure that there are NO existing threads on the problem you're posting.

* ...and, please, proofread the questions, so that they are not nonsense like the question above.

thank you.

Jason, an excellent resource for explanations of the Official Guide quant problems is the Official Guide Companion. You can click on the box to the right to learn more about it.
