107. Two Fathers Gave Their Two Sons Some Money.

Two fathers gave their two sons some money. One gave his son 150 pesos and the other father gave 100 pesos to his son. When the two sons counted their money, they found that all together they had become richer by only 150 pesos. How come?

Solution:

The two fathers are actually a grandfather and a father. The grandfather gives 150 pesos to his son (the father), and then the father gives 100 pesos to his son (the grandson). Although the total amount given is 250 pesos, the increase in wealth is only 150 pesos because the father is also a son, and his original amount is not counted twice.

There are two sons and two fathers. They all go duck hunting and each kill a duck, but they only have ducks. This is because there is one son and his father; the father has a father with him, making two dads and two sons.
