Mary's Dad and GrandfatherLogic puzzles require you to think. You will have to be logical in your reasoning.
For Show and Tell at school, Mary told her class that today was the birthday of both her father and her grandfather and that they were exactly the same age. Her teacher said that was impossible, but Mary insisted she was right. Can you explain how she could be right?
HintMary has two grandfathers.
AnswerMary was talking about her father and her maternal grandfather.
Her father, for example, could be 50 and her mother`s father, her maternal grandfather, could be 50. Her mother is obviously younger than her father.
