Diophantus Puzzle
Student solution? I looked it up om the imternet Let D be the number of years Diophantus lived, and let S be the number of years his son lived. Then the above word problem gives the two equations (1) D = (1/6 + 1/12 + 1/7)D + 5 = S + 4 (2) S = 0.5D Solving this simultaneously gives S = 42 as the age of the son and D = 84 as the age of Diophantus. |
