Currency
One rupee=100 paise. Indian coins come in denominations of 5, 10, 25 and 50 paise and 1, 2 and 5 rupees. Notes are 1, 2, 5, 10, 20, 50, 100 and 500. If you are handed a grubby note, insist on having it exchanged for a newer one. Have a big supply of small bills as change almost does not exist in India
