Mitesh went to teh bank every month, spend Rs. 100 on taking two demand drafts, waited for halp an hour for teh branch to collect the DDs. He sent one dd to his parents and another to his son. He has to Cross check with them whether they have got the dds or not. It took them a minimum of 4 days to receive teh dd and another 3/4 days before they could get the credit in their bank acount.
