Vivek tiwari  (9 years ago)

age of grand daughter is d days d/365 years
and age of daughter is d months d/12yrs
and age of old women is d/7 years

d/7 + d/12 + d/365 = 115years
4380d +2555d + 84d = 115*365*12*7
7019d = 3525900
d = 3525900/7019 = 502
age of old women is 502/7 71.7 years

x=age of grand daughter in days,
age of daughter=y(in months)
z (in years)=age of grandmother
since x=y(in months)
since no.of years of grand mother =no.of weeks of grand daughter,z=x/7
converting them into years=>x/365,y/12,z
given sum of their ages =115
x/365 + y/12 +z=115
x/365 + x/12 +x/7=115
x(1/365 + 1/12 + 1/7)=115
on solving x=505
hence age of old woman =x/7 =505/7=72
age of women=505/12=42
age o child =505/365=1.3(approximately)

Trishla kapoor  (9 years ago)

let x be the no. of days of grand daughter,
x+x*30+x/7*365=115*365
so, x=447.5
no. of years=x/7= 64years--------------->ANSWER
