    B Rs. 2100 Correct Answer Incorrect Answer
    C Rs. 2120 Correct Answer Incorrect Answer
    D Rs. 2025 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the cost price of articles ‘A’ and ‘B’ be Rs. 5y and Rs. 4y respectively Sum of cost price of articles ‘A’ and ‘B’ = 1800 × 2 = 3600 => 5y + 4y = 3600 => 9y = 3600 => y = 400 So, cost price of article ‘A’ = 5y = Rs. 2000 Cost price of article ‘B’ = 4y = Rs. 1600 Selling price of article ‘A’ = 2000 × (122/100) = Rs. 2440 Selling price of article ‘B’ = 1600 + 210 = Rs. 1810 So, average selling price of given two articles = (2440 + 1810) ÷ 2 =  Rs. 2125
