# The father’s age

Let ‘x’ year be the present age of father and ‘y’ year be the present age of son.

Four years hence, it has relation by given condition,

(x+4) = 4(y+4)

x+4 = 4y+16

x- 4y-12 = 0 …(i)

and initially, x = 6y …(ii)

On putting the value of from Eq. (ii) in Eq. (i), we get

6y - 4y - 12 = 0

2y = 12

Hence, y = 6

Putting y = 6, we get x = 36.

Hence, present age of father is 36 years and age of son is 6 years.
