We know little about this Greek mathematician from Alexandria, called the father of algebra, except that he lived around 3rd century A.D. Thanks to an admirer of his, who described his life by means of an algebraic riddle, we know at least something about his life.
Diophantus's youth lasted 1/6 of his life. He had his first beard in the next 1/12 of his life. At the end of the following 1/7 of his life Diophantus got married. Five years from then his son was born. His son lived exactly 1/2 of Diophantus's life. Diophantus died 4 years after the death of his son.
How long did Diophantus live?

• 58yrs 1month 25days
  let Diophantus's age is x
  (x/6)+((5*x)/72)+((55*x)/504)+5+(x/2)+4=x
  78*x=504*9
  x=58.15yrs
  which is equal to '58yrs 1month 25days'
