Hi tanyajain,
I don't know any tutors in Gurgaon, so I can't recommend anyone to you. There are some things that I CAN recommend though, before you start spending too much money.
First, if you want to get some free "math help", then I suggest that you visit Khan Academy (
www.khanacademy.org) - it's a friendly site that makes the process of learning a bit more "fun" and "game-like" and less "dry and academic." You should focus on the basic Algebra, Arithmetic and Geometry materials.
Second, there's no way for you, a tutor, or a GMAT Expert to know your particular strengths and weaknesses until you take a FULL-LENGTH CAT. Thus, you can study for a bit on your own, if you like, but you MUST take that CAT and take it soon. That initial score result will help define your strengths and weaknesses and will point out the areas that you need to focus on.
From your prior post, it's not clear what GMAT resources you've used. You named 3 GMAT companies, but it's not clear what materials you studied with, how long you studied, etc. There also happen to be plenty of OTHER options besides the ones offered by those 3 companies, so you might not have done enough research into the possibilities yet.
GMAT assassins aren't born, they're made,
