Question
A trader marks an article 60% above its cost price.
During a sale, he gives a discount of 15% on the marked price and still makes a profit of Rs 360 on the article. Find the cost price and the selling price.Solution
ATQ, Let cost price = C. Marked price = 1.60C Discount 15% ⇒ Selling price S = 1.60C × (1 − 0.15) = 1.60C × 0.85 = 1.36C Profit = S − C = 1.36C − C = 0.36C Given: 0.36C = 360 ⇒ C = 360 / 0.36 = 1000 So: Cost price = Rs 1000 Selling price = 1.36 × 1000 = Rs 1360
