Hi divya . Well you hadnt mentioned your family income so i m not sure that you are under which category as all National institute of technology have fee waiver format according to your family income so i m considering your family income is greater than 5 lac and as per that detain without including mess and hostel your fees for just tution and all co curicullar activities will be around 6 lac and 40 thousand rupess and including the mess and hostel charges it will go around it will rise up to around 8 lac and 60 thousands . So overall your charges for 4 year of your btech career will be around 9 lac for sure .

Hope it helps
