English Translation

The age of all three is 140 Years.

The age of   Grandson in  number of months is equal to age of Grandfather in years.

The age of  Grandson in  number of days is equal to age of father in weeks.

Tell me how many years is Grandson, Father and Grandfather?

A.

Lets solve line by line. Let the age of GS, F, GF be x, y, z years.

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
