How muc does the cinese x-visa cost for Nepalese people?

I have already received a JW202 and the admission form from the university in china. And i ave already done physical examination in Nepal itself also. I have already made N.M.C also. So how much does it take(in Nepalese rupees) to apply for Student X? And how much time does the embassy of China in Nepal take to put a X type in my passport?
