    Question

    A dealer marked his goods 50% above the cost price and

    sold it after two consecutive discounts of 10% and 20%. If he had marked it 40% above the cost price and sold it after a discount of 20%, then he would have earned Rs. 300 more. Find the cost price of the goods.
    A Rs 7500 Correct Answer Incorrect Answer
    B Rs 7200 Correct Answer Incorrect Answer
    C Rs 7000 Correct Answer Incorrect Answer
    D Rs 8000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the cost price of the goods be Rs. ‘y’. So, the original marked price of the goods = Rs. 1.5y Original selling price of the goods = 1.5y × 0.9 × 0.8 = Rs. 1.08y New marked price of the goods = Rs. 1.4y New selling price of the goods = 1.4y × 0.8 = Rs. 1.12y According to the question: 1.12y – 1.08y = 300 0.04y = 300 y = 300 / 0.04 y = 7500 So, the cost price of the goods = Rs 7500
