    B Rs.20,000 Correct Answer Incorrect Answer
    C Rs.30,000 Correct Answer Incorrect Answer
    D Rs.35,000 Correct Answer Incorrect Answer

    Solution

    ATQ,   Let, the initial salary of the person be Rs. '100x'.   Initial expenditure of the person = 0.70 X 100x = Rs. '70x'   Initial savings of the person = 100x - 70x = Rs. '30x'   New salary of the person = 1.20 X 100x = Rs. '120x'   Savings of the person remains the same.   So, 70x + 6000 = 120x - 30x   Or, 90x - 70x = 6000   Or, 20x = 6000   So, x = 300   So, the initial salary of the person = 100x = 100 X 300 = Rs.30,000
