1500(1+20/100)^3
1500(6/5)^3
=216*12 = 2592

Hi bubbly,

Just wanted to know if you are facing any problem with these questions or you are just posting for the sake !!

Don't get me wrong, since these are very basic question, so I would recommend you to go through basics before you start attempting questions. That will boost your confidence and performance as well.

The problem here on BTG is that due to so many threads its difficult to keep track of good questions. We should make optimum use of forum.
Of course, you can ask your doubts here. Since, I don't see any doubt or any approach that you tried out for this problem, I am not sure how much the solution posted by "kvcpk" helped you.

I am on a break !!

Also, since these are clearly not GMAT questions, you should be posting the source. If not, you run the risk of being banned from the forums for wasting people's time.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
