ANSWER is 300 not 300.5 as given according with gate solution. average seek time = ( 0 +1+2....+499)/500=249.5 for moving from 1st track to 1st track seek time =0 for moving from 1st track to 2nd track seek time =1 .................... so on for moving from 1st track to 500 track seek time =499

option (D) Explanation Avg. time to transfer == Avg. seek time ++ Avg. rotational delay ++ Data transfer time Avg Seek Time given that : time to move between successive tracks is 1 ms1 ms time to move from track 11 to track 1:0ms1:0ms time to move from track 11 to track 2:1ms2:1ms time to move from track 11 to track 3:2ms3:2ms .. .. time to move from track 11 to track 500:499ms500:499ms Avg Seek time =∑0+1+2+3+...+499500=∑0+1+2+3+...+499500 =249.5 ms=249.5 ms Avg Rotational Delay RMP :600:600 600600 rotations in 6060 sec one Rotation takes 60/60060/600 sec =0.1=0.1 sec Avg Rotational Delay =0.12=0.12 { usually Rotation time2Rotation time2 is taken as Avg Roational Delay } =.05sec=.05sec =50 ms=50 ms Data Transfer Time One 11 Roatation we can read data on one complete track . =100×500=50,000=100×500=50,000 B data is read in one complete rotation one complete rotation takes 0.10.1 s ( we seen above ) 0.1→50,0000.1→50,000 bytes. 250250 bytes →0.1×250/50,000=0.5 ms→0.1×250/50,000=0.5 ms Avg. time to transfer == Avg. seek time ++ Avg. rotational delay ++ Data transfer time =249.5+50+0.5=249.5+50+0.5 =300 ms
