Có hai thùng một thùng chứa được 11 gallon và thùng còn lại chứa được 7 gallon. Nước được dùng thoải mái, làm thế nào để nước còn lại trong thùng đúng 1 gallon và làm thế nào để còn lại đúng 2 gallon. Nhờ mọi người giúp nhe'!
The Perfect Pour
Suppose that you have two buckets which hold 11 and 7 gallons, respectively. The buckets are empty, but you have access to an unlimited amount of water. You may fill either bucket from the pump, pour it from one bucket to the other until it is empty or until the other is full, or empty full buckets down the drain. Is it possible to obtain 1 gallon of water? Is it possible to obtain 2 gallons of water?
