Q: Nothing is known about the personal life of the ancient Greek mathematician Diophantus except for the information in the following: “Diophantus passed 1⁄6 of his life in childhood, 1⁄12 in youth, and 1⁄7 more as a bachelor. Five years after his marriage was born a son who died four years before his father, at 1⁄2 his father’s (final) age.” How old was Diophantus when he died?
