Question

In a class of 'N' number of students the number of girls is 'm' ..write a program to input the value of n and m.. find the percentage of boys and girls in the class

Answer 1

 the total number of students be x

Percentage of female students = 44%

So, percentage of boys = 100 – 44 = 56%

Number of boys = 42

56% of x = 42

or (56 * x)/100 = 42

or x = 4200/56 = 75

Answer 2

Answer:

THIS PROGRAM IS WRITTEN BY USING INPUT STREAM READER

//To find and display the percentage of boys and girls

import java.io.*;

class number

{

public static void main(String args [ ])throws IOException

{

InputStreamReader read=new InputStreamReader(System.in);

int n,m,b;

double perg,perg ;

System.out.println(" Enter number of student and girls");

n=Integer.parseInt(in.readLine ( ) );

m=Integer.parseInt(in.readLine ( ) );

b=n-m;

perb=(double)b/n*100;

perb=(double)m/n*100;

System.out.println("Percentage of Boys="+perb);

System.out.println("Percentage of girls="+perb);

}

}
