Hey Pragati.

Tge eligiblity criteria for admission through IIFT Entrance exam is to have a Bachelor’s Degree of minimum 3 years duration from a recognised institute with 50% marks in Graduation. There is 5 % relaxation in case of  SC/ST/PWD candidates, hence they need 45% marks. As no relaxation in favour of OBC candidates is required, then you'd require a minimum aggregate of 50% marks in graduation.

Best of luck
