Hey!

15% quota is termed as the All India quota. Students who have cleared a particular range of marks are eligible for this . This enables a student to get admission on his/her merit at any college all over the country. The merit is highest in 15% quota.

85% quota is the state quota which is generally lower than All India merit. The student belonging to a particular state is eligible for this as it is the state quota. This reserves 85% of the medical seats of a particular state for students of that state alone and increases the chances of the aspirant getting a seat in his state of domicile…

Hope this answers your question… :)
