          Answer & Explanation
         Answer: B) 60 yrs         
         
Explanation: 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.
