Question

son present age is one third his father 12years son age will be 20 years less than his father father age find their present ages​

Answer 1

Answer:

10 and 30

Step-by-step explanation:

Let son's present age be S and father's present age be F

Given, S = F/3

After 12 years, S+12 = F+12-20

S+12 = F-8

S = F-20

F/3 = F-20

2F/3 = 20

F = 30

S = 10

Answer 2

Step-by-step explanation:

Let the present age of son =x

Then, the present age of father =3x

According to the question,

The age of son after 12 years =x+12

And the age of father after 12 years =2(x+12)

Therefore,

3x+12=2(x+12)

3x+12=2x+24

x=12

So, the present age of son is 12 years and present age of father is 36 years.
