Question

find their present ages???

Answer 1

I guess x is equal as 12

Let present ages be : 3x for father
X for son

After 12 years : 3x+12
2(x+12).

3x+12. = 2x+24
3x-2x = 24-12
X. = 12

Son is 12 and father is 36

Answer 2

Let Rahul's present age be x
Father's age is 3x
After 12 years,
Rahul's age = x+12
Father's age=3x+12
According to question,
3x+12=2(x+12)
=>3x+12=2x+24
=>x=12
So, Rahul's present age is 12 years
Father's present age is 36 years
