How many marks, 50th ranker in ca final exams gets???

Hi everyone, 

Can anyone please tell as to how many marks a 50th ranker in CA Final Exams gets? I know it may vary from the attempt to another, but please tell in general. And if possible please tell how many marks a 50th Ranker got in Nov. 2011 and May, 2012 CA Final exams or in any earlier exams.

I will be really grateful to you if you can help!

Thanks in anticipation.
