He earns of profit equal to the selling price of 5 articles.
To find out,
The cost price of each article.
Selling price of 20 articles =Rs. 6000
Hence, the selling price of one article =600020
Hence, profit = selling price of 5 articles =5×300
We know that, C.P.=S.P.− profit

So, the cost price of one article =450020
