Dear Nur, it ideally should not create any issues because it is just one letter. But when you get your admission and seat, the papers might have a different name than the one in the 10th admit card. You havent mentioned which one is correct. If the 10th admit card has correct details, its netter to get an affidavit done stating that you go by both the names. That way there wont be issues at a later point in time.
