Hello Kaveer, 

All the colleges you mentioned have good placement opportunities. But NIT Rourkela has the the record for the highest employee package received by students in transportation among the choices you have provided. But the average package of VNIT Nagpur is more than Rourkela. This means that even though Rourkela has the record for the highest package,  the total number of students who get good packages in VNIT is more than NIT ROURKELA. 

Hope this helps :)
