Correct Answer: 2 years
Solution : Given: The present age of the son = 6 years The father's present age is five times the age of his son, ⇒ Father's present age = 6 × 5 = 30 years
Let's assume that after Y years, his father's age will be four times his son's age. After Y years, Father's age = (30 + Y) years, his son's age = (6 + Y) years
According to the given statement, ⇒ 4 × (6 + Y) = (30 + Y) ⇒ 24 + 4Y = 30 + Y ⇒ 4Y – Y = 30 – 24 ⇒ 3Y = 6 ⇒ Y = 2
So, after 2 years the age of the father will be 4 times as old as his son. Hence, the fourth option is correct.
