The total sales of the top three firms are $78 million, and the sales from the fifth to the twenty-fifth firms are $60 million. Adding these together gives $138 million. Since the total sales for all 25 firms are $150 million, the difference, which is the sales for the fourth largest firm, is $150 million - $138 million = $12 million.
