While walking through the deepest jungle of the amazon, Steve the explorer came across a mystical tomb. He went closer and it read:
"Here lies two faithful husbands, with their two faithful wives,
Here lies two grandmothers along with their two granddaughters,
Here lies two dad's along with their two beloved daughters,
Here lies two mothers along with their two lovely sons,
Here lies two maidens along with their two charming mothers,
Here lies two sisters along with their two amazing brothers.
All were born legitimate, with no incest."
Steve, then checked and saw that there were only 6 graves in total
How was this possible? Steve needs your help to figure it out.
Solution:
If two widows, each having a son married the son of the other widow, and then by the consummation of marriage, both the couples had a daughter, all the aforementioned relationships will turn to be true.
