How to find nro number?

Tell me CA's member ship no of with whom articleship done/ongoing & Name of candiadate, i will tell you nro

first of all thanks for reply Mr. Pankaj ji

actually i wanted to find the Nro number of a student who was sittting with me in ca final exam nov 2014. I just know only his/her examination roll number that's it. 

Then, sorry dear.

I truly support diya's opinion ...  and that's d only way to find someone's NRO no ... 

other option is get that person's pin no as well ... result day pe Roll no and Pin no submit karna ... 

and Voila  You'll get her result along with NRO no 

Thank's a lot for your "valuable" advice....
