    A 25% Correct Answer Incorrect Answer
    B 37% Correct Answer Incorrect Answer
    C 62% Correct Answer Incorrect Answer
    D 35% Correct Answer Incorrect Answer

    Solution

    ATQ,

    Monthly savings of Raju initially = 13500 – 9000 = Rs. 4500

    Increased monthly income = 1.17 × 13500 = Rs. 15795

    Increased monthly expenditure = 1.07 × 9000 = Rs. 9630

    Increased monthly savings = 15795 – 9630 = Rs. 6165

    Percentage increase = [(6165 – 4500)/4500] × 100 = 37%
