The simplest and most complicated math problem in history One summer in the late 1970s, a famous mathematician from Fudan University in Shanghai strolled down the street to buy watermelons.

This kind of topic just confuses the reader and cannot be thought according to the calculation of the topic.

In fact, the mother-in-law who sells melons gets 50 cents, the grandson gets 4 points, and the buyer pays 50 cents and 4 points. No problem.

It can be said that the final ownership of 60 cents is: 6 cents for buying melons (60 cents at first, 54 cents actually paid), 4 cents for grandchildren and 5 cents for selling melons.

As long as the thinking is clear, this kind of topic is not difficult.
