      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 = 0.80 X 100x = Rs. '80x'   Initial savings of the person = 100x - 80x = Rs. '20x'   New salary of the person = 1.10 X 100x = Rs. '110x'   Savings of the person remains the same.   So, 80x + 2000 = 110x - 20x   Or, 90x - 80x = 2000   Or, 10x = 2000   So, x = 200   So, the initial salary of the person = 100x = 100 X 200 = Rs.20,000
