Ved, you haven't mentioned your Category. Nonetheless, you can take admission to BA Economics Honours Programme even if you belong to Jharkhand and do not hold the domicile of UP. SC/ST/OBC Candidates of other States other than UP cannot claim reservation and they will be treated as General. So. if you belong to SC/ST/OBC you can apply for this programme but you will be treated as General Category Candidate. In the faculties of Law, Arts , Commerce, Science and Fine Arts, admission to UG programmes is through merit scored in the entrance exam. To be eligible for BA Economics Hons for University of Lucknow, you should have completed your Intermediate or Equivalent examination with a minimum aggregate of 60%. It is 60% for General Category and OBC and it is 55% for SC/ST. This aggregate is based on the total  marks of all subjects. We would request you to visit the official website for its prospectus for more information: http://lkouniv.ac.in/site/writereaddata/siteContent/202006031424517817UG_brochure_2020_updated.pdf And just to answer your question, though you belong to Jharkhand, you are eligible for pursuing BA Economic Hons from University of Lucknow based on the fact that this University also gives admissions to Out of State Candidates and you have 75% aggregate in your 12th, more than that is required. Hope this helps.
