Answer / dinesh kumar
let x be the avg age of each person in the family ten years
back...
so total age=6x
after 10 years i.e,now the total age of the family =6x+60
let grand father age as y
then the average of the family=(6x+60-y)/5
(bcoz grand father has expired and the new born baby has no
age at present)
according to the given question (6x+60-y)/5=x
bcoz x is the avg age bfore 10 years.
while calc the equation according to the presnt age we have
to add 10 to the result....
so the answer is 70

Answer / chandrima sinha
the time from marriage till now is 10 yrs.Average age will
increase by 10 yrs.
total no. in family is 6. So sum will increase by 6*10=60
the age of newly born is 0. since no change in
average .hence age of father when he died = 60
