Question

There is one grandfather, father and his son, their total age is 140 years; son's months= grandfather's years. ;. son's days = father's years. Please find age of everyone. ​

Answer 1

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.
