Task queues, which allow for asynchronous performance, are an important part of modern processing architectures. Information about a system consisting of several batch processing queues is given. Each queue has three parameters: 1. the maximum number of tasks it can process in a single batch
2. the time it takes to process a single batch of tasks in that queue
3. the number of tasks the queue must process

Given this information, calculate the minimum time needed to process a set of tasks by the system.
