Question 53

The cost price of an article is 25% less than its selling price. What is the profit or loss percentage?

Solution

The cost price of an article is 25% less than its selling price.

Let's assume the selling price of an article is 100y.

cost price = 100y of (100-25)%

= 100y of 75%

= $$100y\times\frac{75}{100}$$

= 75y

profit percentage = $$\frac{selling\ price - cost\ price}{cost\ price}\times 100$$

= $$\frac{100y-75y}{75y}\times100$$

= $$\frac{25y}{75y}\times100$$

= $$\frac{1}{3}\times100$$

= 33.33% profit
