Hello Harsh, 

Talking about these two colleges then none of them offers a secure and good placement. After doing some research i found out that only 34% gets placed in ARYA college and that too from CSE branch only. But here is some positive thing for you and that is if you have guts and dedication you can always get a good placement with a real really good pakage from these teo college. Till now i found only AMITY patna good over ARYA college.

I hope you will find my answer helpful. 

All the best.
