Question

grand fathrer father and his son their total age is 140 the age of grandfather in yearsis equal tothe age of thegrandson in month and the days of grandson age is theage in week of the father then find out their ages in year​

Answer 1

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

SON = 7 years

FATHER = F = 7*7 = 49 years

GRANDFATHER = GF = 12*7 = 84 years
