A father told to his son that, "I was three times of your present age when you born." If the father's present age is 48 years, how old was the boy 4 years ago?
Father was three times his son's present age when he was born,
F - S = 3S
F = 4S (or) 4S = 48 (or) S = 12
Now, age of son before 4 years = 8 years.
Hence, option B is the correct answer.
