Question

My grandson is about as many days as my daugher in weeks, and my grandson is as many months as I am in years. My grandson, my daughter and I together are 120 years. Can you tell me my age in years ?

Answer 1

hope it helps you

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 = 120%2F20

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
