Answer 1

Question:-

➡ Write a program input marks of 3 subjects calculate and print total and percentage if percentage is more than equal to 60 print "pass" else print "hard work needed".

Program:-

import java.util.*;

class PassFail

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

double a, b, c, p;

System.out.println("Enter your marks in three subjects...");

a=sc.nextDouble();

b=sc.nextDouble();

c=sc.nextDouble();

p=a+b+c;

System.out.println("Total Marks you scored: "+p);

p=p/3.0;

System.out.println("Percentage scored: "+p);

if(p>=60)

System.out.println("You passed the exam.");

else

System.out.println("You have failed. Hard work is needed. ");

}

}

Answer 2

Answer:

import java. util. *;

class Marks

{

public static void main(String ar[])

{

Scanner sc=new Scanner (System.in);

System.out.println("Enter marks of 3 subject") ;

int a=sc.nextInt() ;

int b=sc.nextInt() ;

int c=sc.nextInt() ;

double p=0.0;

p=((a+b+c) /300) *100; //calculating percentage....

if(p>=60.0)

System.out.println("Pass") ;

else

System.out.println("Hard work needed") ;

}

}

Explanation:

Note:-

1. formula of percentage is Sum/Total*100
2. Since we know we have to find percentage, it has to be declared in "double" type variable
