    D Rs.35,000 Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ,   Let, the initial salary of the person be Rs. '100x'.   Initial expenditure of the person = 0.65 X 100x = Rs. '65x'   Initial savings of the person = 100x - 65x = Rs. '35x'   New salary of the person = 1.40 X 100x = Rs. '140x'   Savings of the person remains the same.   So, 65x + 5200 = 140x - 35x   Or, 105x - 65x = 5200   Or, 40x = 5200   So, x = 130  So, the initial salary of the person = 100x = 100 × 130 = Rs.13,000
