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.

• 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.

• 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

• 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

• 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

• 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
