Congrats, you have secured good percentile in MAT. Before joining any institute you must have to check three parameters, parameters are 1) Placement 3) Faculties and 3) Infrastructure. I can suggest you few institutes which are accepting MAT score because my friends and cousins are either studying there or have passed out.
NIT Warangal - As all we know NITs are premium government institutes for engineering, this institute is well known for Management studies also. Their recent year highest package was 6LPA.
Lovely Professional University - One of my friends is passed out from here in 2016, now he is working with an MNC as a state head of their sales. Their last year placement also good, the highest package was 21 LPA. Recently Amazon hired few students at a package of 28 LPA. Fortunately, I have the link so sharing with you.

You can read it yourself for a better understanding. LPU has its own test, LPUNEST (National Entrance and Scholarship Test) and this may help you to get scholarship also if you are scoring well.
XIME - This is one of the best institutes to study management studies. Their recent year highest package was 14 LPA.
Christ University - This is one of the top university in South India, their recent year highest placement was 14 LPA.
Hope this information will help you. Best wishes.
