A mathematician wrote the following in his will:
My wife will receive a third of the inheritance, my son a fifth, my oldest daughter a sixth and my little daughter € 9,000.
Who will receive more money from the inheritance?
If we call X to the total inheritance, we can deduce the following equation:
From here we get that x = 30,000 so the woman receives the most money of inheritance:
€ 10,000, his son € 6,000, his eldest daughter € 5,000 and his youngest daughter € 9,000.
