Answer: Father's age is 36 years.
Son's age is 12 years.
Step-by-step explanation:
Let the present age of the father be x.
Therefore, the present age of son will be x/3.
After 12 years,
Age of father will be x+12.
Therefore age of son will be x/3 +12.
According to the question,
x/3+12=1/2*x+12
x/3+12=(x+12)/2
2 (x/3+12)=x+12
2 (x/3+36/3)=x+12
2 [(x+36)/3]=x+12
Multiplying LHS by 2 and transposing 3 to RHS,
2x+72=3x+36
72-36=3x-2x
36=x
Age of the father is 36 years.
Age of son is 12 years.
