Answer 2

Answer:

Gain Percentage = 5%

Step-by-step explanation:

The ratio of cost of price and selling price of an article is 20 : 21

Let the cost price of an article be 20x and the selling price of an article be 21x

We need to find the gain percentage of the article.

Now, Gain = Selling price - Cost Price

⇒ Gain = 21x - 20x

⇒ Gain = x

Now, Gain percentage = x/20x × 100

                                       = 1/20 × 100

                                       = 5%

Thus, Gain Percentage = 5%
