The fees for a 3-year B.Com (Bachelor of Commerce) with Computer Applications in a government college in India can vary quite a bit depending on several factors. These include the specific state where the college is located, the particular college itself, and whether the college is autonomous or affiliated with a state university.

Generally, you can expect the annual fees for such a program in a government college to be significantly lower than in private institutions. A rough estimate would place the annual fees anywhere from a few thousand Indian Rupees up to Rs.20,000 to Rs.30,000. Some government colleges, especially those in smaller towns or rural areas, might have even more affordable fees, possibly ranging from Rs.1,000 to Rs.5,000 per year. On the other hand, well-established and sought-after government colleges located in larger cities might have slightly higher fees, but they would still typically be considerably less expensive than private colleges, where annual fees can easily range from Rs.30,000 to several lakhs.

To get the most accurate information about the fees for a B.Com Computer Applications program in a specific government college, it is highly recommended to visit the official website of that particular college.
