Question
JustLee Books has a problem: Book storage space is filling up. As a solution, management is considering limiting the inventory to only those books returning at least a 55% profit. Any book returning less than a 55% profit would be dropped from inventory and not reordered. This plan could, however, have a negative impact on overall sales. Management fears that if JustLee stops carrying the less profitable books, the company might lose repeat business from its customers. As part of the management's decision-making process, it wants to know whether current customers purchase less profitable books frequently. Therefore, management wants to know how many times these less profitable books have been purchased. ["recently" removed] Determine which books generate less than a 55% profit and how many copies of these books have been sold. Summarize your findings for management, and include a copy of the query used to retrieve data from the database tables.
Explanation / Answer
It is not the good idea to stop selling the books which makes less than 55%. This surly results the drop of sales and the repeated customers also doesn't buy.
I think rather than less than 55% make it as 20%. Then this might get some space for books. Even though the profit is not more than 50% but any where between 35 - 50 is not at all a small one.
Query to retrieve the books less than 55% is below
Select book_id, book_name, count(copies_sold) from book_database where profit<55 group by book_id;
