    Solution

    ATQ,   Let, the initial salary of the person be Rs. '100x'.   Initial expenditure of the person = 0.50 X 100x = Rs. '50x'   Initial savings of the person = 100x - 50x = Rs. '50x'   New salary of the person = 1.30 X 100x = Rs. '130x'   Savings of the person remains the same.   So, 50x + 9000 = 130x - 50x   Or, 80x - 50x = 9000   Or, 30x = 9000   So, x = 300   So, the initial salary of the person = 100x = 100 X 300 = Rs.30,000
