Answer»

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%
