Different name in my certificates from my father's documents

My father's name in his Aadhar is "Rakesh Kumar", but in my all documents its written "Rakesh Mahto". Father's name in my 10th,12th & Graduation is the same. But my father has a different name in Aadhar and Pan. I am studying and want to do UPSC and want to do my Masters from Central University like IIm's. If I make an Affidavit from notary will it help that these two persons is same. No one from my family has gone into jobs and central universities that's why my parents were not aware of this. If I produce my documents at these places in which names are same in all my certificates, will they also to bring father as they want to check his document as well?
