Final answer:
To find the selling price of the articles, calculate the cost price of 25 articles as Rs 960. Then, set the selling price equal to the cost price plus the profit. Simplify to find the selling price per article as Rs 44.80.
Step-by-step explanation:
To find the selling price of the articles, we need to first calculate the cost price of 25 articles. Since the shopkeeper earns a profit equal to the cost price of 5 articles, the profit made is equal to the cost price of 5 articles, which is Rs 800/5 = Rs 160. Therefore, the cost price of 25 articles is Rs 800 + Rs 160 = Rs 960.
Now, we can find the selling price of the articles. Let's assume the selling price of each article is Rs x. So, the total selling price of 25 articles is 25x. Since the shopkeeper earns a profit equal to the cost price of 5 articles, the selling price would be equal to the cost price plus the profit, which is 960 + 160 = 25x.
Simplifying the equation, we get 1120 = 25x. Dividing both sides by 25, we find x = Rs 44.80. Therefore, the shopkeeper would have sold the articles for Rs 44.80 each.
