The tuition fee can be anywhere around 15-16 lakhs. The hostel and mess expenses will be around 20-25K per term depending on your usage of the mess (how much are one's expenses in the night canteens/special dishes at meals etc.)

Since you haven't mentioned specific IIM i would say approximately, Because it varies from one to other.

It would be around 20k to 25k aproximately per term, so for a year it would be around 45k to 50k.

Hope this helps!

Dear please specify the question clearly.
