    A Rs. 1514.25 Correct Answer Incorrect Answer
    B Rs. 1014.25 Correct Answer Incorrect Answer
    C Rs. 1510.25 Correct Answer Incorrect Answer
    D Rs. 1514.75 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the cost price of articles ‘A’ and ‘B’ be Rs. 7y and Rs. 3y respectively Sum of cost price of articles ‘A’ and ‘B’ = 1200 × 2 = 2400 => 7y + 3y = 2400 => 10y = 2400 => y = 240 So, cost price of article ‘A’ = 7y = Rs. 1680 Cost price of article ‘B’ = 3y = Rs. 720 Selling price of article ‘A’ = 1680 × (122.5/100) = Rs. 2058 Selling price of article ‘B’ = 720 + 250.5 = Rs. 970.5 So, average selling price of given two articles = (2058 + 970.5) ÷ 2 =  Rs. 1514.25
