    Question

    Two gadgets, ‘P’ and ‘Q’, were sold for Rs. 2800

    each. The gain on gadget ‘P’ is equal to the loss on gadget ‘Q’. If the cost price of gadget ‘P’ is Rs. 1400 less than that of gadget ‘Q’, find the cost price of gadget ‘P’.
    A Rs. 2150 Correct Answer Incorrect Answer
    B Rs. 1100 Correct Answer Incorrect Answer
    C Rs. 2100 Correct Answer Incorrect Answer
    D Rs. 2000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the cost price of gadget ‘P’ be Rs. x

    Therefore, cost price of gadget ‘Q’ = Rs. (x + 1400)

    According to the question,

    2800 – x = x + 1400 – 2800

    Or, 2x = 2800

    Or, x = 1400

    Therefore, cost price of gadget ‘P’ = Rs. 1400
