There are a room of two available in St. Xavier's College and the figure was roughly around 1 lakh per annum as per the last year stats. Many prefer staying in Paying Guest rooms or outside hostel as well as that can be considered cheaper. But hostel also serves mess food ie 5 meals per day.

Refer to the site below for more details about the same..
