During the admission the general rank is required to get sit in the college.there are two ranks one is all India rank(AIR) another is cast wise rank.But in the time of admission you get sit as per your general all India rank.as your cast rank varries as per student on that cast appear.so it is impossible to say the all India rank as per your cast rank.

I think your general rank may around 2 lakh.

Not fully sure

Hope it helps!
