Answer 1

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.
