Question
A store offers a 30% discount on a product and still
makes a 10% loss. If the difference between the discount amount and the loss is Rs. 360, find the selling price needed to gain a 15% profit.Solution
ATQ, Let the cost price of the article is Rs. '100x' Selling price of the article = 0.90 × 100x = Rs. '90x' Marked price of the article = (90x/0.70) = Rs. (900x/7) Loss incurred = 100x - 90x = Rs. '10x' Discount given = (900x/7) - 90x = Rs. (270x/7) So, (270x/7) - 10x = 360 Or, (200x/7) = 360 Or, x = 12.6
So, required selling price = 1.15 × 100 × 12.6 = Rs.1,449
