Java loan calculator

Question

You take a loan from a friend and need to calculate how much you will owe him after 3 months.
You are going to pay him back 10% of the remaining loan amount each month.
Create a program that takes the loan amount as input, calculates and outputs the remaining amount after 3 months.

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 remain=amount;

for(int i=0;i<3;i++){
int payment= (90/100);
remain*=payment;

}
System.out.println(remain);

}
}

//why is my code dont give any output?, what is wrong

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
int k = amount;
int persent;
int payment;
for (int i = 0 ; i < 3; i++) {
persent = k * 10 /100;
payment = k - persent;
k = payment;
}
System.out.println(k);

}
}

Answer 2

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 = 0;x < 3;x++) {
amount -= ((amount * 10) / 100);
};
System.out.println(amount);
}
}
//Simple

Answer 3

remain = 0.1 * remain
amount - =remain

Answer 4

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
int loan;
//your code goes here
for(int i=1;i<=3;i++)
{
loan =amount/10;
amount-=loan;
}
System.out.println(amount);
}
}

Answer 5

You need to calculate 10% of the current amount and subtract that 10% from the current amount for each iteration of the loop. Also, if there is a fractional part (part after the decimal) you will need to round the percent up to the next whole number before subtracting from the current amount.

Answer 6

thanks for help
I got the answer from google but I still dont understand why I cant directly multiples the amount(100000) with 90/100,

this is the correct answer

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
int remain = amount;
for (int i = 0 ; i <3; i++) {

int payment = (int)Math.ceil(10/100.0*remain);
remain -= payment;
}

System.out.println(remain);
}

}

Answer 7

Working code:

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 payment = 0;
int month = 1;
do{
if (amount%10 == 0){
payment = amount/10;
amount = amount - payment;
}
else {
payment = amount/10 +1;
amount = amount - payment;
}

month++;

} while (month <= 3);

System.out.println(amount);

}
}

Answer 8

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=3; x!=0; x--){
amount *= 0.9;
} System.out.println(amount);
}
}

Answer 9

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 payment , remainingAmount;
for(int i=0; i<3; i++ )
{
payment=(10/100)*amount;
remainingAmount=amount-payment;
System.out.println(remainingAmount);
}

}
}

Answer 10

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 pay;
for(int i = 0; i < 3; i++)
{
pay = (10*amount)/100;
amount -= pay;
}
System.out.println(amount);
}
