Câu hỏi:
If the only frying pan in the house is large enough to cook two pancakes at a time and pancakes take one minute to brown one side, how can you make three pancakes in three minutes?
Đáp án:
Pour two pancakes and brown the first side. After the first side is done, flip one, take the second off, and pour the third pancake. After another minute, take the first one off, flip the third one, and put the second one back on. Cook both pancakes until finished.
