It would be better if you take chemical in IIT guwahati. IIT provide a good exposure to student in not academics but also in other activities also. And you wanted to do mba in future, so IIT definitly enhances your confidence which is very necessary for mba.

Also, if there is any problem in future in mba, IIT provide a good placement than IIIT hyderabad.
