    Solution

    Let the cost price and marked price of the article be Rs. 5x and Rs. 8x, respectively
    According to the question,
    8x – 5x = 240
    Or, 3x = 240
    Or, x = 80
    Therefore, cost price of the article = 5x = Rs. 400
    Marked price of the article = 8x = Rs. 640
    Selling price of the article = 640 – 180 = Rs. 460
    Required profit percentage = {(460 – 400)/400} × 100 = 15%
