  • Options
  • A. 14 years
  • B. 16 years
  • C. 12 years
  • D. Data inadequate

  • Correct Answer
  • 14 years 

    Explanation

    Let us assume father age is F and his son age is S.
    According to question,
    The sum of the ages of father and his son is 4 times the age of the son,
    F + S = 4S
    F = 3S.............. (1)
    Average age of father and son is 28.
    (F + S)/2 = 28
    F + S = 56
    Put the value of F from equation from (1),
    3S + S = 56
    4S = 56
    S = 14 years
    Age of Son = 14 years.
