Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
Even I got this Q on my GMATprep.. I had almost chosen a wrong answer before it suddenly flashed to me that square root of any positive number greater than 1 is always greater than 1, be it 1.0001 or 10000. So, in this question, 2+GT1+GT1= GT 4
I may also point out that I got this question after 10 straight right answers. So IMO either this question is 51 level or this is a test question. If its the former then well, a reason to feel good isn't it :D
