Question

A shopkeeper offers 10% discount on the printed price of a mobile phone. However, a customer has to pay 9% GST on the remaining amount. Write a program in Java to calculate the amount to be paid by the customer taking printed price as an input. 

Answer 1

import java.util.*;
public class U5_Q2{ 
public static void main(String args[])
{
Scanner obj = new Scanner(System.in);
double price, dprice, gst, amt;
System.out.println("Enter the printed price of the mobile"); 
price = obj.nextDouble(); // printed price
dprice = price − 10.0 / 100 * price; // discounted price
gst = 9.0 / 100 * dprice; // gst 
amt = dprice + gst; // discounted price + gst
System.out.println("Discounted price : " + dprice); // optional statement
System.out.println("Amount payable including gst: " + amt);
}}
