I was married 10 years before my wife was sixth member of my family and now I have a baby and today father died and the average age of my family was same as it was 10 years before. Find my father's age when I was married.

• Let the Father be x years when he died
  
  Average Age 10 years ago be A
  
  Total Age 10 years ago = 6*A
  
  Total Age after 10 years(Just before father's Death) = 6A + 6*10 = 6A + 60
  
  Father Died and Baby was born => the Total number of people in the family is Same (6)
  Baby born today so age of baby = 0
  
  (6A +60 - x)/6 = 6A/6
  => A + 10 -(x/6) = A
  => x/6 = 10
  => x = 60
  
  Therefore we can conclude that the father was 60 years old when he died.
