Let +c+ = his cost for the shoes
+c+-+.2c+=+2800+
+.8c+=+2800+
+c+=+3500+%7D%7D%0D%0A-------------------%0D%0AHis+loss+was+%0D%0A%7B%7B%7B+.2c+=+.2%2A3500+
+.2c+=+700+
-------------------
As % of his selling price:
+%28+700%2F2800+%29%2A100+=+25+
25%

His loss is 0.2*x, where x is his cost price.


His selling price is 0.8*x.


The question is about his loss as a percentage of his selling price, which is %280.2%2Ax%29%2F%280.8%2Ax%29%29%2A100 = %280.2%2F0.8%29%2A100 = 0.25*100% = 25%.

Answer. 25%.
