A) 50 years
B) 60 years
C) 70 years
D) 80 years
E) Indeterminate
If x was average age 10 years ago, then total age 10 years ago = 10x.   Total age of 6 persons before death of father = 10x+60   Total age of 6 persons ( excluding father and adding son of zero age) after death of father = 60x as average of family is x again.   Hence age of father at time of death = x+60-x = 60 years   ANSWER:60 years
