Question
Cost price of article ‘B’ is (250/7)% of selling price
of article ‘A’. Article ‘A’ is sold at 40% profit and cost price of article ‘A’ is Rs. 15 more than that of article ‘B’. Find the cost price of article ‘B’ if the cost price of article ‘A’ is the same as the selling price of article ‘B’.Solution
ATQ,
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
