So ur grandson is 7 years old, ur  son is 49, ur 84.

Grandson in days as old as son is in weeks just means your son's age is 7 times your grandson's age. Similarly, you are 12 times older than your grandson (grandson in months as old as you are in years).

x + 7x + 12x = 140; x = 7; 7x = 49; 12x = 84.
