  Let cost price of 1 kg of material be 1Re.
While buying, he has bought 1.1 kg of material for 1Re.
While selling, he sells 0.9kg of material at 1Re.
Hence, he would sell 1.1kg of material at 1.1/0.9 Rs = 11/9 Rs.
Total gain = (11/9 - 1)/1 = 2/9 Rs = 200/9 % = 22.22%
Please correct me if wrong.

  After purchasing shopkeeper not only sell 1.1 kg but actually he sell (1.1+10%of1.1)=1.21 kg because of false weight. so profit percent= ((1.21-1)/1)*100%=21%
