    Explanation:

    From I: [(x-8) + (x+4)]/2 = [(x+4) + (x+6)]/2 – (x-17)
    => x = 24
    Average age of Akbar = 24 + 4 = 28 years
    This statement alone is sufficient.
    From II: [(x-8) + (x+4)]/2 = [(x+4) + (x+6)]/2 – 7
    This cannot solve the question.

    Hence, option 5 is the correct answer.
