Missing DollarLevel pending
Jack, Joseph and Jacqueline were going to buy a New Year’s Eve gift for $30. Each put $10 in. When they pay the money to the cashier; the cashier realized that the price of the gift which Jack, Joseph and Jacqueline were purchasing was not 30$ but $25. Joseph was the brightest. He told the cashier to keep two dollars, and give one dollar to each of the buyers: Jack, Joseph and Jacqueline. The question is, now that each buyer has paid $9, and Philippe, the cashier, has taken $2, (3×9+2=29) who took the one dollar missing?
