    E None of these Correct Answer Incorrect Answer

    Solution

    Let the cost price of articles ‘A’ and ‘B’ be Rs. 4y and Rs. 5y respectively Sum of cost price of articles ‘A’ and ‘B’ = 6300 × 2 = 12600 => 4y + 5y = 12600 => 9y = 12600 => y = 1400 So, cost price of article ‘A’ = 4y = Rs. 5600 Cost price of article ‘B’ = 5y = Rs. 7000 Selling price of article ‘A’ = 5600 × (120.5/100) = Rs. 6748 Selling price of article ‘B’ = 7000 + 600 = Rs. 7600 So, average selling price of given two articles = (6748 + 7600) ÷ 2 =  Rs. 7174
