A room contains one grandfather, one grandmother, two fathers, two mothers, four children, three grandchildren, one brother, two sisters, two sons, two daughters, one father-in-law, one mother-in-law, and one daughter-in-law. What is the smallest number of people who are there?
Any help will be appreciated.
This is probably wrong, but I would suppose four- two men and two women. Both men are fathers, one is a grandfather, one is a brother to somebody, both are sons of somebody, one is a father-in-law. Both women are mothers, both are someone's sisters and someone's daughters. One is a mother-in-law and one a daughter-in-law. All four people are someone's children and three of them are someone's grandchildren.
