Age Problem
There was a grandmother in a village that had a grandchild. Upon asking her grandchild’s age she told that she is as older as many days old as her daughter’s age in weeks and as many days as her own age in years. The sum of the ages of three is 130. Then how old is the child?

-
- let the ages be a,b and c of grandmother,daughter and granddaughter respectively.
we have 3 equations as:
52b=365c
and a=365c
also,a+b+c=130
solving this,i m getting age of granddaughter about 127 days. - 10 years agoHelpfull: Yes(20) No(6)
- let grandchild's age be x days.
let grandchild's age be x days.
grandmother's age=x*365 days.
daughter's age=x*7 days.
x*365+x*7+x=130*365
=>x=127 days. - 10 years agoHelpfull: Yes(14) No(1)
- let ages be x,y and z
z be age of grandchild
y be age of daughter
x be age ofgrandmother
these ages are in days ....
then z= y/7
nd z=x/365
nd x+y+z= 130 *365
then z cones out to be 127.21

- let child age be x daughter be y and grandma be z
so we get equations x = 52y and x = 365z
and x+y+z=130
solve this
so child age is 127 days - 10 years agoHelpfull: Yes(2) No(0)
- sum of there ages is 130 but what is the unit yr month or day is not given so data indiquite

- grandmother's age= x;
mother's age =y;
x/365 = y/(12*7)=grandchild's age(in year);
(x/365)+(((12*7)/365)x)+x=130;
solving, x=105.44 year, therefore grandchild's age is 0.28 year, i.e 3.46 months - 10 years agoHelpfull: Yes(0) No(0)
- grandmother's age= x;
mother's age =y;
x/365 = y/(52)=grandchild's age(in year);
(x/365)+(((52)/365)x)+x=130;(considering 130 as years)
solving, x=113.51 year, therefore grandchild's age is 0.31 year, i.e 3.73 months - 10 years agoHelpfull: Yes(0) No(1)
- let grandmother age =x yr
father age =x weak
child age =x day
according to question ,
x yr + x weak+ x day = 130 day
convert it into day all
1 yr=365 day
x yr =365x day
similarly 1yr= 365 day
52 weak=365 day
1 weak=365/52 day
x weak=(365/52)*x day
so put that in above equation
365 x+(365/52)x+ x= 130
(19080+365+52
sum of age 130 yr
let grandma age is p yr
her daughter age is p wk
her grandchild age is p day
according to ques we will write as follow
(365 p + 7 p + p) days = 130*365 days
p=127.21 days
