A shopkeeper marked an article ‘A’ 20% above the cost price and sold it for Rs. 1008 after giving a certain discount while he sold an article ‘B’ for Rs. 2520. If cost price of article ‘B’ is Rs. 1800 and profit percentage earned on selling article ‘B’ is 60% more than discount percentage given on selling article ‘A’ then find the cost price of article ‘A’.
Percentage profit earned on selling article ‘B’ = [(2520 – 1800)/1800] × 100 = 40% So, percentage discount given on selling article ‘A’ = 40/1.60 = 25% So, marked price of article ‘A’ = 1008/0.75 = Rs. 1344 Cost price of article ‘A’ = 1344/1.20 = Rs. 1120
