En el curso de Java hay un error en el problema de calculadora de prestamos

Question

Alguien puede revisar y ver mi error

Answer 1

Me explican por qué 90/100?

Answer 2

I think it is a rounding problem.

Your calculation looks like this:
por= amount *10/100;
amount -=por;
Mine looks like this:
amount = (int)(amount * 0.9);

I make it an int after each calculation.

Answer 3

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here
int months = 3;
for (int i = 0; i < months; i++)
amount = amount * 90 / 100;
System.out.println(amount);
}
}
