Let , 
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 =120/20 
g = 6 yrs is grandson's age
