A shopkeeper marked his article 25% above its cost price
and offered a discount of 30%. If cost price of the article is Rs. 560, then find profit or loss of the shopkeeper on selling the articleSolution
Marked price of the article = 1.25 × 560 = Rs. 700 Selling price of the article = 0.7 × 700 = Rs. 490 Loss = 560 – 490 = Rs. 70
