Old women said that number of days of my grand daughter is equal to the number of months of my

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)

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

why x/7 = grandmotherage
explain clearly
10 years agoHelpfull: Yes(1) No(0)
since x is in number of days so to convert them into no of weeks we divide it by 7
10 years agoHelpfull: Yes(0) No(0)
x+x/52+365x/(52*12)
x=71.68
9 years agoHelpfull: Yes(0) No(0)

Old women said that number of days of my grand daughter is equal to the number of months of my daughter and my age in number of years is equal to the number of weeks of my grand daughter. Sum of their ages is 115. Find the age of the old woman.
