Solution

Let assume that he buys 1000 gram of quantity at 1000 Rs

So, Cost Price of 1 gram = 1 Rs

Now as it is mentioned that he is selling only 850 gram in 1000 Rs

So , selling Price of 1 gram = $$\frac{1000}{850}$$ = Rs 1.1764

So profit percentage = $$\frac{SellingPrice-CostPrice}{CostPrice}$$ = $$\frac{1.1764-1}{1}\times100$$

= 17.64 % = $$17\frac{11}{17}$$%
