Two mothers and two daughters went shopping together, spending a total of exactly thirty dollars. They split the cost evenly, and each person spent exactly ten dollars. How is this mathematically possible with only three people present?
The three people are a grandmother, a mother, and a daughter.
A grandmother is a mother (to the middle generation), and the mother is also a daughter (to the grandmother). This creates two mothers and two daughters across only three generations.
