As you have mentioned that you want to know what is fees structure for the sc students. The fee structure not including provision  me tell you that the total fees for iiit delhi in course of 4 years is 14L including your hostel fees

there is fees waiver provision for SC-ST student. In some IIITs , it is like 75% tution fees waiver while in other it is 50% Tution fees waiver

Hope this will help you
