Revised return

I have efiled my and my moms returns online. However both our returns have been sent for revised returns. So in my case, I got the refund for my earlier return. Whereas as per my revised return I am to receive 1000 more as refund. Will this amount be credited back and how much time does it take for the processing of revised return. Similarly I had made some mistake while submitting my moms returns and filed for revised returns on the same day itself. However she has not recieved any refund uptill now ie. date of efiling is 29/07/2016.
