Question

Present age of father is 28 years more than his son's age father's age becomes two times of his son's age after 20 years then what is the present age of the father

Answer 1

Step-by-step explanation:

Let the present father's age be x

Let the present son's age be y

Now,

y = x - 28 ....1

After 20 years

Father's age = 20+x

Son's age = 20+y

20+x=2(20+y)

20+x=40+2y

x=20+2y .....2

From 1 and 2, we get

x=20+2(x-28)

x=20+2x-56

x-2x=-36

-x=-36

x=36

Father's present age = 36 years
