cost price. The article is sold at 25% discount such that the seller earns a profit of Rs. 25. Find the marked price of the article.Solution
Let the cost price of the article be Rs. x. Then, marked price of the article = Rs. x + 400 Selling price of the article = 0.75 (x + 400) (given that discount is 25%) ATQ; 0.75 × (x + 400) = x + 25 Or, 0.75x + 300 = x + 25 Or, 0.25x = 275 So, x = 1100 So, marked price of the article = 1100 + 400 = Rs. 1500
