Hey Abhijit:)

No worries,This is a common Issue.While filling the UPSC form, just use your name as exactly as it appears in your 10th Marksheet, since UPSC considers the 10th marksheet as the main record .Even if your aadhar has a different order it usually doesn't create issues,but if later UPSC finds a mismatch during verification,they may ask for supporting proof(like affidavit,gazette or corrected ID) .So,the safest step is to use 10th marksheet for now,then try to correct your aadhar or keep an affidavit ready to avoid any future problem.

Hope you'll find this helpful!
