Put four cakes in, two of them fry for two minutes and the other two fry for one minute. Then fry for one minute, take it out, put the other two in, two minutes later (the total time is the same), the other two can be turned over, and three minutes later, the two are finished. Two somersaults in the back. At the same time, put the fried ones in, wait for two minutes, and the other four will finish eating at the same time.

The pervert of this question is that we think it only takes one minute because one side is fried for two minutes and the other side is fried for two minutes. Don't make assumptions about life experience. The fourth grade of primary school is as simple as possible. Ha ha.
