    Answer: (4) Rs. 500

    Explanation:-
    Let the original price of the chair be Rs. X

    If a chair sold for Rs. 600 at the profit of 20%, 
    Then, X x 120/100 = 600
     6 X/5 = 600
    6 X = 600 x 5
     X  = 3000/6
    X = 500

    Then, the original price of the chair is Rs. 500.

    Hence, the correct answer is option (4) Rs. 500.
