    A Rs. 20 Correct Answer Incorrect Answer
    B Rs. 14 Correct Answer Incorrect Answer
    C Rs. 22 Correct Answer Incorrect Answer
    D Rs. 15 Correct Answer Incorrect Answer

    Solution

    Let cost price of article ‘A’ = Rs. ‘x’ = selling price of article ‘B’ Selling price of article ‘A’ = 1.40 × x = Rs. ‘1.4x’ So, cost price of article ‘B’ = (5/14) × 1.4x = Rs. ‘0.5x’ ATQ, x = 0.5x + 15 Or, 0.5x = 15 Or, x = 30 So, cost price of article ‘B’ = 0.5x = 0.5 × 30 = Rs. 15
