A shopkeeper sold an article after offering two successive discounts of 15% and 10%, respectively. The marked price of the article is Rs. 2200. If the cost price of the article is 2000, then find the profit/loss percentage in the whole transaction.
Marked price of the article = Rs. 2200 Selling price of the article = 2200 × 0.85 × 0.9 = Rs. 1683 Cost price of the article = Rs. 1683 So, loss percentage = [(2000 – 1683)/2000] × 100 = 15.85%
