1.- The following people were at a family gathering: a grandfather, a 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 could have been at the gathering?
The smallest number is 7. Remember that a grandfather is also a father, a mother can also be a daughter—and even a daughter-in-law. The people at the gathering were as follows: an elderly couple, their son and his wife, and their three children—a boy and two girls.
