Question

Father is 3 times as old as his son .After 12 years he will be twice as old as his son .Present age of son ​

Answer 1

Answer:

Step-by-step explanation:

Let son's age be x.

Father's age will be 3x.

After 12 years,

Son's age will be x+12

Father's age will be 2(x+12).

3x +12= 2(x+12)

3x+12= 2x+24

3x-2x=24-12

x=12
