Absolutely i'm agree with Mr. Nuli

Make sure you send the correct ITR-V to CPC bangalore.

you should send all the ITR V's to CPC bangalore... that is original and two revised..

Is it needed to send the original return acknowledgement , when we have revised the return.As revised return replaces the original return.This is what I understand!

yes...u only need to send the revised ITR-V (Acknowledgement)..not the old one
