(#M40000668) TCS QUESTION Keep an EYE

a man has age in years equal to his daughters age in months and
daughter age is equals to his grand daughter age in weeks and her age
in weeks total age of 3 members is given 91.find out the mans
age

Solution

let the age of man (in years) = x
age of daughter = x (in months) = x/12 years
age of grand daughter = x/12 (in weeks) = x/(12*52) years
now x + x/12 + x/(12*52) = 91
on solving we will get x = 83.876 years = 84 years (approx)
so age of man = 84, that of daughter = 84/12 = 7 years
and that of grand daughter = 7 weeks (approx 0 years)
