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 βAβ = Rs. βxβ = selling price of article βBβ Selling price of article βAβ = 1.40 Γ x = Rs. β1.4xβ So, cost price of article βBβ = (5/14) Γ 1.4x = Rs. β0.5xβ ATQ, x = 0.5x + 15 Or, 0.5x = 15 Or, x = 30 So, cost price of article βBβ = 0.5x = 0.5 Γ 30 = Rs. 15
