Questions with " Solve x in terms of Y"

by trinity22 » Sun Dec 11, 2011 9:28 am
In my gmat prep, I noticed I was getting a lot of "solve x in terms of Y" questions.. I could handle a couple of them, but I started to wonder if I am getting those right because I kept getting them one after the other. (I didn't finish the test, so I wouldn't know ifI got them right or wrong). Has anyone noticed this also? IS there a pattern as to when they come up? (i.e. when you are doing well or when you are doing poorly?)


I would love to know if anyone has any strategy about how to solve these types of question? any Tricks/Traps? I usually solve them algebraecally, but sometimes I am not confident in my approach.

THoughts?

Hi Trinity,

I have given a couple of GMAT tests but never encountered a situation where these questions kept getting one after another. Just a one off may be ! Coming to your question on tricks of solving, see if this helps -> https://catman3000.hubpages.com/hub/Rear ... verse-only

If you can post "solve X in terms of Y" questions, you feel you need help with, I will help you with the approach.

That's an interesting question. As far as I know, "x in terms of y" questions are just like any other format, and are not meant to appear any more frequently as a result of getting them correct/incorrect.

I think of "x in terms of y" as just "what is x"? By the nature of the question, the answer will be "in terms of y" but we can ignore that as we approach.

For questions dealing with variables, always look for opportunities to pick numbers for either x or y (or both!). You may also be able to plug in or backsolve for these Q's.

You may want to do a BTG or Google search for "GMAT x in terms of y" and create a WordDoc with 20 of these types of questions. Look to see how often you can pick numbers or backsolve with them. Taking a few seconds at the top to consider your approach rather than just dive into setting up equations may yield better results!
