venkatesh I will suggest your to file your income tax return at your  permanent address. 

Otherwise if your file your return then their may come problem in processing of your ITR if filed manually, No problem if filed Online

According to me you have to submit in Bangluru( bangalore). Let see other's friend's reply...

D best is to file it online

Yes, filing tax return online is the best option to excerise since it will automatically captures ITO ward as per PAN database with Income tax

You should file your return on your pan baise Word because in case of refund it will create problem and your refund is not process so its better to file your retrun on your pan baise word !!!
