My friend Charles works in a post office and he sells stamps. One day a man walked in and slamming seventy five rupees on the counter requested,

"Please give me some 2 rupees stamps, six times as many one rupee stamps, and for the rest of the amount make up some 5 rupee stamps."

Charles thought for a few moments and finally she handed over the exact fulfilment of the order to the man.

How did he do it and how many stamps of each type did he give to the man ?

For every two rupee stamp there has to be 6 rupees worth of 1 rupee stamps, making a total of 8 rupees. To be able to fill the rest with 5 rupee stamps you need to have a multiple of 5 of these. With eight you can make forty.

So the amount of stamps are:
5 lots of 2 rupee stamps
30 lots of 1 rupee stamps
and
7 lots of 5 rupee stamps.
