Answer 1

Answer:

import java.util.*;

class program

{

public static void main ( string args [ ])

{

Scanner sc = new Scanner ( System.in)

System.out.println("Input the cost price of the article")

int cp=sc.nextInt()

System.out.println("Input the selling price of the article")

int sp=sc.nextInt()

if(sp>cp)

int profit = sp - cp ;

int profit percent = (profit/cp)*100;

System.out.println("Profit ="+profit)

System.out.println("Profit percent =" + profit percent)

if(sp<cp)

int loss = cp - sp;

int loss percent = (loss / cp)*100;

System.out.println("Loss ="+loss)

System.out.println("Loss Percent ="+loss percent )
