Question
The cost price of article 'B' is (250/7)% of the selling
price of article 'A'. Article 'A' is sold at a 40% profit, and the cost price of article 'A' exceeds the cost price of article 'B' by Rs. 15. Additionally, the cost price of article 'A' is equal to the selling price of article 'B'. Determine the cost price of article 'B'.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
