Hello Gayatri,
RCOEM jas only two categories they consider for admission and that is general and Hindu minority. It does not have any specific OBC category. The cut off marks for general/open category last year was 90.35 and that for OMS category (for students from other state), the cut off was 91.8.
Hope this helps.
