2.

A man is going to a car auction. All purchases must be paid for in cash. He goes to the bank and

draws out Rs. 25,000.

Since the man does not want to be seen carrying that much money, he places it in 15 envelopes

numbered 1 through 15 such that he could count any amount from 1 to 25000 using combinations of

some envelopes. Each envelope contains the least number of bills possible of any available

currency. (for example, no two tens instead of a twenty). The possible currency denominations are

1,2,5,10, 20, 50 and 100.

At the auction, he makes a successful bid of Rs. 8322 for a car. He hands the auctioneer envelopes 2,

8, and 14. After opening the envelopes the auctioneer finds exactly the right amount. How many

ones (one rupee notes) did the auctioneer find in the envelopes?
