Question

A dealer allows his customers a discount of 25% and still gains 25%. Write a program to input the cost of an article and display its selling price and marked price.

[Hint: SP = `((100 + p%)/100)` * CP and MP = `(100/(100 − d%))` * SP]

Answer 1

    import java.util.*;
    public class KboatCalculatePrice 
    {
        public static void main(String args[])
          {
              Scanner in = new Scanner(System.in); 
        System.out.print("Enter cost price of article: "); 
        double cp = in.nextDouble();

        int disc = 25, profit = 25;
        double sp = 0.0, mp = 0.0;

        sp = ((100 + profit) / 100.0) * cp;
        System.out.println("Selling price of article = Rs. " + sp);

        mp = (100.0 / (100 - disc)) * sp; 
        System.out.println("Marked price of article = Rs. " + mp);
    }
}
