Given :
• Father is three times as old as his son.
• In 12 years time he will be twice as old as his son.
To find :
• Present age of father and son
Solution :
Let us assume the present age son be x years.
→ Fathers age = 3(Age of son)
→ Father's age = 3(x)
→ Father's age = 3x
Their age after 12 years :- [Add 12 years to the ages of father and his son.]
→ Son's age = x + 12 years
→ Father's age = 3x + 12 years
According to the question,
→ Father's age = 2(Age of son)
→ 3x + 12 = 2(x + 12)
→ 3x + 12 = 2x + 24
→ 3x - 2x = 24 - 12
→ x = 12
→ The value of x = 12 years
Substituting the value of x in the ages we've assumed :-
→ Son's age = x = 12 years
→ Father's age = 3x
→ Father's age = 3(12)
→ Father's age = 36 years
Therefore, the age of father is 36 years and the age of his son is 12 years.
Answer → Option (4) :-
Father : 36 years, Son : 12 years
