Name discrepancy

Dear sir, I appeared for an SBI interview yesterday. However, there is one serious issue I've been facing sir and I have nobody to guide me on this and I sincerely request you to please guide me so that I don't end up missing this opportunity. The issue is - My name is Varun Kumar Singh. My name in 10, 12 and graduation degree appears as "Varun Kr Singh" While in my Adhaar card it is spelled as "Varun Kumar Singh" so going by the adhaar card, I filled my application form by the name similar in Adhaar card as Varun Kumar Singh. (I also clarified with ibps and they asked me to do as given in the identity card) I took an affidavit stating that both names belongs to the same person but they didn't accept it. I asked them what I should do so that it doesn't create problems in my appointment, they didn't give any clear answer. One of the staff members just said "correct your adhaar card" So I am not sure how credible this advice is because the concerned person just didn't answer as to what I should do. I have a concern if I do correct it in my Adhaar then would it not be an issue that all your documents have Kr while your application form states Kumar (and application form can't be changed now) I feel so helpless sir. Please guide me sir what is the way forward. I cannot just afford to lose this opportunity. I need this job
