Sabita, 

I would recommend you to take Nagpur EEE or Jaipur Mechanical. 

The average package offered at lower branches in DTU is 5-6 lacs/ annum and placement percentage is also about 70-80%.

Whereas Placement percentage of NAGPUR EEE is abput 90% and average package goes upto 8 lacs per annum. 

The case is almost similar in JAIPUR MECHANICAL. 

And with branches like MECHANICAL AND EEE you have better future opportunities but that is not the case with lower branches like production engineering and like. 

The rest depends on you. 

Hope it helps.
