Hello Sujata, Both FMS Delhi University and XLRI Jamshedpur are great institutes for management studies in India. Both have got great top notch faculties and have some of the best placement records in India.
They are constantly in the top 10 management schools in the country. However the financial outcome of FMS is best in the country, that is the money you invest vs the money you are expected to make after completion of the degree.
Best of luck.
