In my opinion, perhaps it will not pose any problem in case the candidate's and father's name is correctly mentioned in the documents. The author may therefore concentrate upon preparing for the competitive examinations for getting selected for PSU jobs etc. In case the author is able to score very high in the competitive examination and come among toppers, then perhaps the focus and attention of the officials verifying documents will shift to merit instead of on missing trivialities in the documents. Moreover since the particulars like mother's name etc. are not asked even in the application form for any job, the same is not likely to matter much.
