Answer 1

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
for (int x = 1; x <= 6; x++){
amount = amount * 9 / 10;
}

System.out.println(amount);

}
}

Answer 2

carefully read the condition, it says that 10 percent is not deducted from the original amount

Answer 3

Иван Чикyнов 's code is right but in case you want the result to be EXACT (or with decimal places)
//just replace
int amount = scanner.nextInt();
//with
double amount = scanner.nextInt();

Answer 4

Иван Чикyнов how did think about it in this way:
Amount= amount *9/10;

Answer 5

amal 01
9 / 10 = 0.90 = 90%
So multiplying by its 90% means subtracting by its 10%.

e.g.
10 * 9 / 10 = 10 * 0.9 = 9 (which is equal to 10 - 1 and 1 is the 10% of 10) and so on
