The ratio of the selling price and the cost price of an article is 1 : 2. What is the loss percentage?
The ratio of the selling price and the cost price of an article is 1 : 2.
Let's assume the selling price and the cost price of an article are 'y' and '2y' respectively.
loss percentage = $$\frac{cost\ price - selling\ price}{cost\ price}\times100$$
= $$\frac{2y - y}{2y}\times100$$
= $$\frac{y}{2y}\times100$$
= 50%
