Question

The term "utilization" denotes the fraction of time a resource is busy. Let's say your workload gradually increases, from you not being busy at all, to the point where you are now busy just less than half the time, meaning your utilization is now approaching 50%. Let's further say that your workload will continue to increase from here. If your workload quadruples from its current level, how many extra people should you hire to be able to handle all the work (assume that any person you hire will be exactly as productive as you)?

4 people

Explanation:

Since the utilization at 50% means half work done then if its quadruples, it means the work rate will increase to 200%. Only 4 people would be able to match same strength as the initial self.
