Dear aspirant!

Hope you are doing well ! If you tell us the fees of one student and other data which you have whatever it is then only we will be able to give you the correct fee structure of 250 students . Isn't it ? So while posting th le question ,try to read it carefully whether it is meaningful or not . It creates difficulty to us to answer such questions. Do the same what I said above in the comment section of this question.

Hope you understand!

Thanking you
