How many students share a room in IIT Mandi hostels?

My friend stays at IIT Mandi's hostel for girls and she has a room for herself and the facilities are good. It is an excellent institute, being an IIT, it ranks #31 on the NIRF Engineering ranking list. In 2018, girls had to share rooms and two girls stayed in one room. IIT Mandi has two campuses called the North and South campuses respectively. 

You may wish to note these down:

• You'll be allotted a hostel on the basis of availability, and single, double, and triple occupancy rooms are available.
• The south campus hostels give residence opportunities mostly to Ph.D., MTech, and other postgraduate researchers. The rooms are available with sharing options of 2-3 sharing capacity.
• The north campus has residential facilities for undergraduate B.Tech, B.Sc students. Rooms here are available as shared options as well as single occupancy.
• MTech and Ph.D. students can avail the single-room facility at the north campus too if needed.

Here's a table highlighting the important points about the hostels-

As you can see there are more buildings available for boys but the living costs and basic amenities are available in all formats of residencies, be it single, double, or triple.
