Step-by-step explanation:
Let the age age of the son be x.
Therefore, the age of the father=x+30.
After 12 years,
Son's age=x+12
Therefore father's age=3*(x+12)
=> x+12+3*(x+12)=x+12=x+30+12
=>x+12+3x+36=2x+54
=>4x+48=2x+54
=>4x-2x=54-48
=>2x=6
=>x=6/2=3
Ans) The son's age is 3 years and the father's age is 3+30=33 years.
