    Explanation:

    Let the income of Mr.X = y
    From I and II
    15% of y = 4500 => y = 30000
    From II and III
    4/5th of expenditure = 20400

    => Expenditure = Rs. 25500, Savings = Rs.4500
    Income = 25500 + 4500 = 30000
    From I and III
    4/5 of 85% of x = 20400
    x = 30000
    Thus any two of the three statements, are sufficient to answer the question.

    Hence, option 5 is the correct answer.
