Hii Abirami!
If you mention the name of the Institution or the College where you want to pursue BSc in Nursing, it will be more helpful for us to provide you with accurate information. Nevertheless, on an average, the fees ranges from INR 20,000 to INR 1.5 Lakhs per year. But, this may vary depending on certain factors and also, whether the College is a government College or a private one.
Hope this helps.
Good luck!
