Hi Sneha,
The salary package for CSE students, and for that matter any branch's students depends upon the college from which they have done their engineering. If someone has done his/her engineering from a bad college then s/he might not get placed at all. However, if you have done it from top IIITs/NITs/IITs, then you could hope for anywhere between 12-40 lakhs per annum or even more depending upon the students(exceptionally well students).
Therefore, placements are very relative field and you have to be in a good college to get good placements. There are other institutes also, other than IITs/
NITs with good placements like BITS, VIT, etc.
Here are some important links for you to get further information about these colleges:-
