    Answer: (3) Rs. 80, Rs. 60 

    Solution:-
    Let the cost of one article be X and cost of another article be Y.

    A discount of 15% on one article is the same as a discount of 20% on another article.
    Then, X x 15/100 = Y x 20/100
    3 X = 4 Y
    X/Y = 4/3

    X/Y = 4 x 20/3 x 20
    X: Y = 80 : 60

    Then, the cost of the two article can be Rs. 80 and Rs. 60.

    Hence, the correct answer is option (3) Rs. 80, Rs. 60.
