Misspelling of father's name but same in all documents?

Respected Sir/Ma'am Kindly help me out to resolve the queries:- Honourable sir/Ma'am, In all my documents ( 10th, 12th Grad. Post grad. ,Adhaar Etc) my father's name spelling is SHAUKEEN but in his Adhaar and in his other documents bear SHOKEEN, (his correct spelling) Sooner, I have to appear for Documents Verification for the central Government job:- Q1) Will it create problem to me? Q2) What is the way out ? Kindly help out! Some selected candidates advised me not to reveal your father's correct spelling to them Because they won't crosscheck father's spelling from father's Adhaar. But I doubt this, Because If they come to know this later, they may cancel the candidature on the charge of hiding the true information. Q3) kindly exlress your opinion on the above? Q4) If I get correction published in Gazette, will I have to correct all my documents? Or Gazette publication itself is enough and no further changes required in all my documents? I will be highly obliged to you all respected ,kindly help. Thanks and Regards
