Is this the topic that the landlord said? An old man in ancient India left his last words to his three sons before he died: property: 19 cows, and gave them to his three sons. The eldest gets half of the total, the second gets a quarter, and the eldest gets a third. How to divide it?

Lend a neighbor a cow, 20. The eldest one gets 10, the second one gets 5, the third one gets 4, and the rest is returned to the neighbors.
