• There is NO demand of managers in the industry. Period.
• The non-top-2000 MBA degree holders from the top Indian business schools find it very hard to get a Rs. 40K+ monthly initial package(+ there is high degree of uncertainty in their job prospects). Simply because, “managing” is an unskilled work and any logical human brain can carry it out, OKishly.
• Whatever placement happens at the Tier-2 MBA colleges in India(like BIT Mesra), are primarily to fool the substandard-private management college graduates, that they have been placed in some company at the position of a manager(with the graduates from better management colleges). But, infact, the owners of such substandard-private management colleges in India are themselves owners of such companies. So, in order to let the management students from substandard-management colleges, feel that they have been placed with the students of better-govt management college graduates, few companies recruit 4–5 graduates from such better-govt colleges at 30–40% better salary than what is given to the graduates from the substandard-private management colleges in India.
• In a way, I am saying that most of the MBA graduates from non-substandard management colleges(like BIT Mesra) remain unplaced !!!
• Most of the management graduates from better-govt management colleges(like BIT-Mesra) have very uncertain future, in terms of almost everything, from career graph, to salary, to job satisfaction, to job security.

So, to exactly answer this question:

1. BIT-Mesra,NIT-R and NIT Silchar management students do not come under top-2000 management graduates of that year.
2. Pay scale- Rs. 15K-35K, with negligible exceptions, which is primarily to fool the management graduates from substandard private management colleges, with whom these exception-cases work with.
3. The statistics provided by such colleges are generally manipulated and not worth considering.
