Hi Akshii,

             I hope you are doing good. Now coming to your query, Among RBA and EWS reservation Undoubtedly RBA is more beneficial in Jammu because EWS reservation is only 10% whereas RBA reservation in Jammu is 20%. So people with RBA reservation has twice the more chances compared with EWS reservation candidates. St category also has only 10% reservation So ST and EWS reservation have approximately equal benefits.

I hope this helps.

Thank you.
