Which is better, MBA from Jamia Millia Islamia or Jaipuria Institute Of Management, Lucknow?

To be frank, none of the institutes you mentioned are worth joining for an MBA. Jamia is a bad choice for MBA and is likely a tier III institution while Jaipuria is probably tier IV. Jamia Millia Islamia average package for MBA 2022 is INR 8.8 LPA while Jaipuria Institute of Management's average package (2021-2023) is INR 12.34 LPA. The ROI offered is extremely low considering the fact that the cost of an MBA program is almost double the pay package you receive. 

MBA is best taught at tier-1 and tier-2 colleges like IIM AND FMS. If you go for an average B School you will end up with a useless degree and a loan to repay. 

However, if you are left with only these two options, then Jamia is still a better choice than Jaipuria as the fees charged are less.
