So, How to calculate the average of marks in math?
A: That’s quite simple, for example, consider you have just completed your sem exams, and the result announced as:
Maths – 75
Science – 55
Operating Systems – 80
Dataware house – 75
Now, sum up all – 285/4 = 71.25 ( Your average marks )
So, your average of entire subjects are = 71.25 ( Formula stated below)

That’s a standard and the only way to calculate your average of marks. Now, check out the following programs.

class AverageMarks
{
public static void main(String arg[])
{
int n=5,avg=0;
int a[]=new int[n];
a[0]=10;
a[1]=20;
a[2]=30;
a[3]=40;
a[4]=50;
for(int i=0;i<n;i++)
avg=avg+a[i];
System.out.println("average of ("+a[0]+","+a[1]+","+a[2]+","+a[3]+","+a[4]+") is ="+ avg/n);
}
}
OutPut :

average of (10,20,30,40,50) is =30
