Hello Dimple,
The eligibility criteria for DU DSE entrance is as follows to get admission in MA. Economics:

• A candidate must be a graduate or post graduate in any subject  from the Delhi University or recognised university.
• Must have secured atleast 60% or it's equivalent CGPA ( candidates belonging to general category) and there will be a concession for reserved candidates.

So if you belong to any reserved category then you are eligible for DU DSE.
I hope this is helpful to you.
