To calculate percentile
|
||
|
|
|
||
|
|
Write a program for the problem: the array of
|
||
|
|
inetegers indicating the marks of the students is
|
||
|
|
given, U have to calculate the percentile of the
|
||
|
|
students aaccording to this rule: the percentile of a
|
||
|
|
student is the %of no of student having marks less
|
||
|
|
then him. For eg:
|
||
|
|
suppose
|
||
|
|
|
||
|
|
Student Marks
|
||
|
|
A 12
|
||
|
|
B 60
|
||
|
|
C 80
|
||
|
|
D 71
|
||
|
|
E 30
|
||
|
|
F 45
|
||
|
|
|
||
|
|
|
||
|
|
percentile of C = 5/5 *100 = 100 (out of 5 students 5
|
||
|
|
are having marks less then him)
|
||
|
|
|
||
|
|
percentile of B = 3/5*100 = 60% (out of 5, 3 have
|
||
|
|
markses less then him)
|
||
|
|
|
||
|
|
percentile of A = 0/5*100 = 0%.
