Question

Question 2: write a java program   

A Hypermarket makes an offer for its customers according to the number of items to be bought as follows:

Number of purchased items	Discount percentage
Less than 25	2.5%
25 – 50	5.0%
51 – 100	6.25%
Greater than 100	7.5%

The hypermarket also adds 2% city taxes to the purchases after the sale discount.

1. Reads from the user the number of items to be purchased and the item price.
2. Calculates and prints the original purchase cost.
3. Calculates and prints the discount amount.
4. Calculates and prints the new purchase cost after computing the discount.

Net Purchase Amount = Purchase amount after discount + City Tax

Answer 1

//importing package which contains Scanner class
import java.util.*;
//class
class Market
{
//main function
public static void main(String args[])
{
int n;
double price,discount,total_cost;
//creating Scanner class object
Scanner s=new Scanner(System.in);
//asking user to enter number of items
System.out.print("Enter the number of items to be purchased: ");
//storing integer input in n
n=s.nextInt();
//asking user to enter item price
System.out.print("Enter the item price: ");
//storing double input in price
price=s.nextDouble();
//calculate and print original purchase cost for n items each having cost as price
total_cost=price*n;
System.out.println("Original Purchase cost: "+total_cost);
//calculate the discount amount
//the below if else control statements are written according to the table given in question
if(n<25)
discount=2.5*(total_cost)/100;
else if(n>=25 && n<=50)
discount=5.0*(total_cost)/100;
else if(n>=51 && n<=100)
discount=6.25*(total_cost)/100;
//case when n>100
else
discount=7.5*(total_cost)/100;
//print the discount amount
System.out.println("Discount amount: "+discount);

//calculate new purchase cost after subtracting discount
total_cost=total_cost-discount;
//printing cost after discount
System.out.println("New purchase cost after discount: "+total_cost);
//calculate net purchase amount after adding city tax of 2%
total_cost=total_cost+(2*total_cost)/100;
//printing cost after adding city tax
System.out.println("Net purchase amount after adding city tax: "+total_cost);
}
