Hello Kunal, 

I am assuming that you are asking for CS branch. Nobody can give you exact and correct figure of heighest package. There have been students who have grabbed a handsome package from JSSATEN campus from time to time , the latest one is a package of INR 14 lac in Kronos , grabbed by 2 students of CSE. As much as i know ,a few people get the pacakge of 8 lpa per year from CSE. Average package for CSE/IT is 3.5 LPA to 4 LPA, but some high paying companies do come for campus placements, paying upto 6 LPA to 7 LPA, such as InfoEdge, Reve Systems, Kronos.

Thank you
