Hi Vidisha,
The integrated first degree course of MSc (Hons) in Economics, the eligibility criteria is that candidates should have passed the 12th class examination of 10+2 system from a recognized Central or State board or its equivalent with Physics, Chemistry, and Mathematics and adequate proficiency in English. So, unfortunately you are NOT eligible for doing humanities in Pilani Campus. I would suggest you to search colleges in DU or any central university.

All the best

Your CAT score is low, but BITS Pilani's MBA follows a profile based selection and it is not just the CAT percentile what is looked upon for admission. So, I would suggest you to apply for it.

Any subjects can be pursued in order to study Hotel Management. It doesn't have any required specialization to do in class 11th and class 12th. To make it easy, you can pursue commerce. It is a good choice of stream to study.
