Question 310264: Grandpa: "My grandson is about as many days as my son is weeks, and my grandson is as many months as I am in years. My grandson, my son and I together are 120 years. Can you tell me my age in years?" Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! "My grandson is about as many days as my son is weeks, and my grandson is as many months as I am in years. My grandson, my son and I together are 120 years. Can you tell me my age in years?"
:
g = grandson's age
s = son's age
m = my age
:
"My grandson is about as many days as my son is weeks,"
s = 7g
:
my grandson is as many months as I am in years.
m = 12g
:
g + s + m = 120
Substitute for m and s
g + 7g + 12g = 120
20g = 120
g =
g = 6 yrs is grandson's age
then
s = 7(6) = 42 yrs is son's age
and
m = 12(6) = 72 yrs is my age
;
:
See if we can prove this:
"My grandson is about as many days as my son is weeks," a
g: 6*365 = 2190 days
s: 42*52 = 2184 days, that's why they said "about"
:
"my grandson is as many months as I am in years."
g: 12*6 = 72 months
