Hello nischal

Placements in nits vary from college to college. In top nits like tirichy, warangal, surathkal you can get a good package for a metallurgy which you will get for a computer science guy in middle or last nits.

So from college to college it differs. 

But where as in a same nit the placements average package would vary like this :

(CSE, ECE, IT) >(MECH, EEE, CHEM) >(CIVIL, Metallurgy, Biotech). 

It would vary in this way, but I cannot make sure that this trend will be followed in every college. But for most of the colleges it will be the trend. 

All the best for your counselling
