Here is a list of processes and their running times in milliseconds:

A:$800,$ B:$600,$ C:$100,$ D:$900,$ E:$300$

If the context switch time is zero, compute the time that it takes for each process to finish assuming that the time slice is set to $100$ms

Process A : Answer $1$ Question $1$ ms

Process B : Answer $2$ Question $1$ ms

Process C : Answer $3$ Question $1$ ms

Process D : Answer $4$ Question $1$ ms

Process E : Answer $5$ Question $1$ ms

What would be the average efficiency of the processor if the context switching time was set to $10$ms$?$ Enter a rounded integer value as your answer. Answer $6$ Question $1$
