Question

A shopkeeper sells two calculator for same price he on 20% profit on an one and suffered a loss of 20% on the other write a program in Java to find his total cost price of the calculator by taking selling prices input ​

Answer 1

Answer:

package com.sample.sample2;

import java.util.Scanner;

public class Main {

   public static void main(String[] args) {

       double cp1,cp2,profit,loss;

       Scanner scan=new Scanner(System.in);

       System.out.println("Enter the S.P of calculators");

       double sp=scan.nextDouble();

       double profitPercent=20,lossPercent=20;

       /* formula for profit percent = profit/sp*100

       * formula for loss percent = loss/sp*100

       * where cp is cost price and sp is selling price

       * profit=(profit percent *sp)/100

       * loss=(loss percent *sp)/100

       * hence by calculating profit and loss we can calculate cp*/

       profit=(profitPercent*sp)/100;

       loss=(lossPercent*sp)/100;

       cp1=sp-profit;

       cp2=sp+loss;

       System.out.println("Cost price of Calculator which the shopkeeper sold on profit: \u20B9"+cp1+

               "\nCost price of Calculator which the shopkeeper sold on loss: \u20B9"+cp2);

   }

}
