Guys,
I did it with similar triangles too..but iam not sure if similar triangles is in the GMAT syllabus.Og doesnt mention it ..neither is there any question on this topic in whole OG. Till now , I havent seen any question on similar triangles property in any of ETS sources. But since this is supposed to be an ETS question, and if it cannot be done in any other way , I have to conclude that similar triangles could be tested in GMAT. Otherwise, i will be wasting my time preparing to cement it's fundamentals.
If anybody can confirm about this, it will be really helpful.Is there no way to do this question except using similar triangles properties?
