I've managed to pull the following data together about our offices nationwide, which I'm hoping you can look at in more detail. I'm keen to understand performance differences, mainly around profit margin, between our northern and southern regions. Please could you let me know how they compare? In case you haven't come across the term, profit margin is the percentage of net income compared to total revenue and is a measure of how efficiently each of revenue is converted into profit. Please could you reply directly to this email with an answer to this question, as well as an outline of your analysis. Many thanks, Cornelius Masilo
