Euler, a famous Swiss mathematician, once asked an interesting question about the distribution of inheritance: Before his death, a father asked his sons to distribute the inheritance as follows.

Solution: Let the second person have X eggs. The first person has (100-X).

The first man said to the second man, "If I had as many eggs as you, I could sell 15 yuan."

It is concluded that the first person sells 15/X yuan per egg.

The second man said, "If I have your eggs, I can only sell them for six and two thirds."

It is concluded that the second person sells 6 2/(100-x) yuan per egg.

Enumerable equation: (100-x) * (15/x) = (62/3 (100-x)) * x.

Solve X 1=60, X2=300 (truncation).

So the second man has 60 eggs and the first man has 40 eggs.
