Answer 2

By selling 5 articles, a man gains the cost price of 1 article. Then the Gain percentage is 20%

Solution:

Given that by selling 5 articles, a man gains the cost price of 1 article

To find: Gain percentage

Let the Cost price of an article be Re 1.

Thus cost price of 5 articles = Rs 5

Profit = Selling price of 5 articles - Cost price of 5 article

Given,

Profit is Cost price of 1 article. Thus

Cost price of 1 article = selling price of 5 articles - cost price of 5 articles

Cost price of 6 articles = Selling price of 5 articles.

6 = selling price of 5 articles [ since cost price of per article is Re1]

$\text { Therefore profit } \%=\frac{6-5}{5} \times 100=20 \%$

Thus the gain percentage is 20%
