You purchased a lottery ticket and suppose you got the first prize of 100,00,000$ or you won in the poker or some contest. The condition from the company is that to get the prize you need to spend 10,00,000$ in one day or they will pay you only 50,00,000 $. The other condition is that if you choose to spend 10,00,000$ in one day then you need to show the receipt or bills for the spendings. So what would you prefer. If first choice then how and where would you spend the money??
