i have scored agri practical 9900. and theory 41000. and vet practical 7700 , theory is 37000. with HK . which one ranking will be considered

For admission, the concerned counselling authority uses the officially defined merit/ranking methodology for that course. The rank generated after combining the applicable examination components is what matters—not whichever individual component has the smaller number.

Therefore:

• Agriculture practical rank 9,900 ≠ final Agriculture admission rank
• Agriculture theory rank 41,000 ≠ automatically the rank used for allotment
• Veterinary practical rank 7,700 ≠ automatically your Veterinary admission rank
• Veterinary theory rank 37,000 ≠ automatically your Veterinary admission rank

Your final counselling rank/category rank shown on the official rank list/allotment portal is the one you should use.

Also, HK reservation can substantially alter your eligibility/competition because seats are earmarked for the relevant Hyderabad-Karnataka/Kalyana Karnataka category where applicable.
