A cottage industry produces a certain number of pottery articles in a day. it was observed on a particular day that the cost of production of each article (in rupees) was 3 more than twice the number of articles produced on that day. If the total cost of production on that day was Rs 90, find the number of articles produced and the cost of each article.

So, let us assume the total number of article = x The coat of an article = 2x + 3 Total cost of production = Number of produced * cost of an... View Article
