Question

one father one grandson one grandfather total ages of all three is 140years.Grandson age is months equal to grandfather age in years. Grandson age is days equal to father age in weeks.Tell the ages of all three persons​

Answer 1

Answer:

Let the age of grandson be x years. So, the age of grandson in months is 12x which s equal to grandfather's age.

Now, the age of son in days is 360x and in weeks is if we divide it by total weeks in the year that is 52 and the result is 360x/52 which is 90x/13 which is also father’s age.

So, as per the question, x+12x+90x/13=140.

So, x=7.02 or roughly 7.

So, the age of grandson is 7, of father, is 49, and of grandfather is 84.

Answer 2

Answer:

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.
