Consider the scheduling algorithm in the Solaris operating system for time-sharing threads.

1. What is the time quantum (in milliseconds) for a thread with priority 15? With priority 40?
2. Assume that a thread with priority 50 has used its entire time quantum without blocking. What new priority will the scheduler assign this thread?
3. Assume that a thread with priority 20 blocks for I/O before its time quantum has expired. What new priority will the scheduler assign this thread?
