Assuming that you are talking about St Xaviers Mumvbai then Yes St. Xaviers college Mumbai does offer Bachelor's in Enonomics . You should have atleast obtained sixty five percent in your class 12th boards to be eligible to apply for this program. admission is on the basis of merit only. you can read this up to resolve all your queries - http://xaviers.edu/main/index.php/economics

You have to apply on their website - http://xaviers.edu/main/index.php/admissions-and-courses

Hope it helps

Thanks
