In a cloud environment, a company is experiencing performance issues due to resource contention among its virtual machines (VMs). The IT team is considering implementing a resource allocation strategy to optimize performance. They have three types of workloads: high CPU, high memory, and balanced workloads. If the total available CPU resources are 1000 MHz and memory resources are 2000 MB, how should the team allocate resources to ensure that each workload type receives adequate resources while minimizing contention? Assume that high CPU workloads require 300 MHz and 200 MB, high memory workloads require 200 MHz and 600 MB, and balanced workloads require 250 MHz and 250 MB. What is the optimal allocation strategy that maximizes the number of VMs running simultaneously?
