Chitkara and Chandigarh University are great options for doing a B.Tech. For MBA, you should not consider these institutes. After completing your degree from these institutes, you won’t be able to get decent job options, unless you have a master’s degree from reputed universities. 

Try to get into Govt. colleges. If you are an engineer, try to improve your skills, make projects, and try to get jobs at MNCs. If you are from a general background, it’s better to prepare for CAT.
