One morning I
west to draw some money from my bank.
The ‘Cashier behind the counter smiled at me and said ‘I’ve got here
money of all denominations. I’ ve got denominations of 1 paise , 5 paise, 10 Paise , 25 Paise, 50 paise , Re 1/-, Rs 2/,
Rs 5/, Rs 10/ , Rs 20/, Rs 50/ Rs 100/, Rs 500 /, - and Rs 1000/-.
How many different amounts of money can I make by taking one
or more of each denomination? What do
you think my answer was?
Answer: 14
