Officially the GSET criteria states:

'Candidates who have secured at least 55% marks (General) (without rounding off) in Master’s Degree OR equivalent examination from universities/institutions recognised by UGC in Humanities (including languages) and Social Science, Computer Science & Applications, Sciences are eligible for GSET Examination'

So keeping this eligibility into consideration you have done management which is a different field.

You can check the complete official eligibility criteria here .

Let me know if any further confusion exists.
