• A

No  • B

Yes, A, B, C  • C

Yes, D, E, G  • D

Yes, A, B, F  • Option : C
• Explanation :
System is in Deadlock due to process D,E,G
So option C • A

13  • B

12  • C

11  • D

10  • Option : A
• Explanation : So, option (A) is correct.

• A

70  • B

14  • C

13  • D

7  • Option : B
• Explanation : To avoid deadlock 'm' >= peak demands(P1 + P2 + P3) i.e. m >= peak demands(2 + 5 + 7) m >= peak demands(14) So, option (B) is correct.

• A

B, A, D, E, C  • B

C, E, D, B, A  • C

E, D, C, B, A  • D

C, B, A, E, D  • Option : B
• Explanation :
We will solve it by minimizing the avg Waiting Time and Take x = 4 BT = Burst or Execution time CT = completion time P = Process AWT = Average Waiting Time AT = Arrival time WT = Waiting time We get minimum average waiting time from the sequence given in option (B)

• A

3  • B

2  • C

4  • D

5  • Option : A
• Explanation : There are 3 context switch. So. option (A) is correct.
