Answer: Option D

Let cost price of the article is = Rs. 100
Marked price is 10% high of cost price mean = Rs. 110
Discount always given on marked price
10% discount of marked price means
$$=\frac{10}{100}\times 110=\text{ Rs}\text{. 11}$$
∴ Selling price = Marked price - Discount
Selling price = 110 - 11 = Rs. 99
$$\begin{array}{rl}& \therefore \text{Loss}\%\\ & =\frac{\text{Cost price}-\text{Selling price}}{\text{Cost price}}\\ & \Rightarrow \text{Loss}\%=\frac{100-99}{100}\times 100\\ & =\frac{1}{100}\times 100\\ & =1\%\end{array}$$
