Let cost price of 1 gm goods = Rs. 1
Letthe shopkeeper purchases 100 gm goods.
Total cost price = Rs. 100
Due to cheating he actually gets = 100 + (10/100) × 100 = 110 gm goods.
Due to cheating at the time of selling the goods, he sells = 110 + 110× (10/100) = 121 gm goods
Total selling price = Rs. 121
Required profit percentage = (121 – 100)/100 × 100 = 21%
