The number of girls sharing a room in the MBA course at Banasthali Vidyapeeth might vary. While there's no definitive public information specifying the exact room-sharing arrangement for MBA students, it's generally expected to be similar to other postgraduate programs in the university.

Typically, Banasthali Vidyapeeth follows a system where multiple students share a room. The exact number could range from 2 to 4 students per room. However, it's essential to note that this information might change over time, and the university might have introduced new hostel facilities or accommodation arrangements.

For the most accurate and up-to-date information, I recommend contacting the admissions office of Banasthali Vidyapeeth directly. They can provide you with the specific details regarding hostel accommodation for MBA students.
