You can actually achieve the answer by trial and error, but the way to calculate it is thus:They told me there would be no math
The age of all three is 140 Years.
So, x + y + z = 140 years
The age of Grandson in number of months is equal to age of Grandfather in years.
So, 12*x = z (multiplied by 12 to convert year to month)
The age of Grandson in number of days is equal to age of father in weeks.
So, 365 * x = (365 * y) / 7
Which becomes => 7x = y
So, replacing value of y and z in original equation:
x + 7x + 12x = 140
20x = 140
I.e. x = GS = 7 years
y = F = 7*7 = 49 years
z = GF = 12*7 = 84 years
You can verify this by adding them up;
7 + 49 + 84 = 140 years.
Do you want another, or does your brain hurt?
