Hello Anil Kumar, thanks for asking this question on this platform.actually on seat allotment there are some predefined qouta in which reservation alongwith state quota comes . according to which if you are from the same state of that college you will get some benefits for it .thanks 

Hey.

Under the home state quota, the seats are reserved for candidates based on their state of eligibility which is basically the state where they have completed their Class 11th and 12th from. Almost 50% seats are reserved for HS quota students.  Other State (or OS) Quota- Under the Other State Quota, the seats are reserved for candidates who belong to any state other that particular  Home state. Around rest of the 50% seats are reserved for OS quota students.  

Best of luck!
