Narendra Patel   (10 years ago)

first we arrange the no such that
1,2,3,5,9
now median is the 3
becose here n=5
hence median=(n+1)/2=3
3rd no
so ans =3

Dear Madhur
For even no:
if there are 2 medians then take them both and find the average. Like if the numbers are 1,2,3,4,5,6 the medians are 3 and 4 so you would add them both together and divide by how many numbers there are in this case 2; you would get 7 and then divide that by 2 and get 3.5 so that is the median in this case.

Total time taken by operator = 2 + 9 + 3 + 1 + 5 = 20

Total number of call taken = 5

Average time per call = Total time taken / Total number of calls taken

= 20/5 = 4

median for odd term= {(n/2)th term + (n/2+1)th term }/2
and median for odd= (n+1)/n
here n=5 so, 5+1/5=6/5=1.2=1 ans
