Old women said no of days of my grand daughter = no of months my daughters is?
And my age in no of years is= no of weeks of my grand daughter . sum of their ages is 115. Find d old women age?

• 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
• 10 years agoHelpfull: Yes(46) No(8)
• let x is the no. of days of grand daughter then
  x+x*30+x/7 *365=115*365 so x=447.5
  so no of year=x/7 =64years
  
• 10 years agoHelpfull: Yes(19) No(15)
• suppose no of days of grand daughter=x
  
  therefore no of weeks of daughter are=x
  no of days of daughter are=30*x (approx.)
  
  weeks of grand daughter=days of grand daughter/7=x/7
  
  therefore age of old women is=x/7 years=365*x/7 days
  
  sum of ages of grand daughter , daughter and old women=(x)+(x*30)+(365*x/7)
  =x(1+30+365/7) ......(1)
  
  and given total age is=115 years=115*365 days ......................(2)
  
  therefore
  x(1+30+365/7)=115*365
  x(83.142)=115*365
  x=(115*365)/(83.142)
  x=504.85~=505 days (grand daughter's age in days)
  grand daughter's age in weeks=505/7=72.14=72
  
  therefore old womens age in years=72 years

• let X be the grandchild year
  So Daughter of Old Woman Age is 365X/12 Yr (365X month)
  Old Woman age is 52X (1year = 52 week)
  
  a to q
  X+365x/12+52x=115
  after solv X= 1.24
  
  Old Women Age= 1.24*52= 64 year approx
• 10 years agoHelpfull: Yes(3) No(3)
• let x is the no. of years of old women.
  then
  A/Q
  x+x/52+7*x/12= 115
  
  on solving we get
  x= 71.76yrs
• 10 years agoHelpfull: Yes(3) No(0)
• Let x is the age of old woman.
  so 365x+7x+30*(7x)=115*365,
  After solving x=72.12 years ans=72.12 years
• 10 years agoHelpfull: Yes(2) No(0)
• let grand daughter days be x
  x365 + x12 + x7=115 yrs
  x=73.76=74 yrs (approx)
• 10 years agoHelpfull: Yes(1) No(4)
• age of old women is 502/7 71.7 years
• 10 years agoHelpfull: Yes(1) No(0)
• let grand daughtr=x yrs,daughtr=y yrs,grand mother= z yrs
  given 365x=y12 and z=52x and x+y+z=115
  substitute,we get x=1.3786 then z=71.6 yrs
  
• 10 years agoHelpfull: Yes(1) No(0)
• we know that , No. of days in year=365
  No. of months in year=12
  No. of weeks in year= 52
  Let, age of grand daughter be X
  age of daughter be Y
  age of grand mother be Z
  Given,
  No. of days of grand daughter = No. of months of daughter
  i.e., 365X=12Y----------(1)
  Age of grand mother in years= No. of weeks of grand daughter
  i.e., Z=52X-------------(2)
  Sum of their ages=115
  i.e., X+Y+Z=115------------(3)
  Solving 1,2&3,
  X=1.378
  Z=52*1.378=71.6years

• let z be the age of grand mother in years, then in weeks, she is 52z weeks.
  Grand daughter is z weeks. and daughter is 28z weeks.
  
  52z+28z+z=115*52
  
  age of grand mother is approx 73 years
• 10 years agoHelpfull: Yes(0) No(0)
• age of grand daughter =x days
  age of daughter =x *30 days
  age of old women =x/7 yrs=365*x/7 days
  x+x*30+365*x/7=115*365
  x=504.85
  age of old women=504.85/7=72.12=73 yrs

• d/360+d/12+d/52(week)=115
  d=70

• 98 years..
  granddau age in days x=y=x/12(mother)
  old z/365=x/7(grsnddaughter)
  x+y+z=115
  
• 9 years agoHelpfull: Yes(0) No(1)
• 23v and 32
• 9 years agoHelpfull: Yes(0) No(1)
• let d days is the age of the grand daughter,then
  d+30*d+d/7*365 =115*365
  solve it
  d=504.8539...
  age of the grandmother is d/7=72.12
