Question
The marked price of an article is Rs. 450 more than its
cost price. The article is sold at 15% 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 + 450’ Selling price of the article = Rs. (x + 15) ATQ; 0.15 × (x + 450) = x + 25 Or, 0.15x + 67.5 – x = 25 Or, 0.85x = 42.5 So, x = 50 So, marked price of the article = 50 + 450 = Rs. 500
