Hii!
The course fees for b.com + LLB as an integrated course varies across India in government and private universities. It may vary from INR 30,000 to INR 2.5 lakhs in public and between INR 1.7 lakhs to INR 2.5 lakhs in private universities.
Per annum, the fees may range from INR 30,000 to INR 2.5 lakhs too, accordingly.
Hope this helps.
Good luck!
