    Ravi sold two items for Rs. 8,400 each. He gained 20% on

    one item and incurred a loss of 20% on the other. What is the difference in their cost prices?
    A Rs.3500 Correct Answer Incorrect Answer
    B Rs.3738 Correct Answer Incorrect Answer
    C Rs.4625 Correct Answer Incorrect Answer
    D Rs.3530 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Cost price of the item sold at 20% gain = 8400 ÷ 1.2 = Rs. 7,000

    Cost price of the item sold at 20% loss = 8400 ÷ 0.8 = Rs. 10,500

    So, required difference = 10500 - 7000 = Rs. 3,500
