Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here
double amt = amount*0.1;
double ramt = amount - amt ;
double amt1 = ramt*0.1;
double ramt1 = ramt-amt1;
double amt2 = ramt1 *0.1;
double ramt2 = ramt1 -amt2;
double amt3 = ramt2 * 0.1;
double ramt3 = ramt2 - amt3 ;
double amt4 = ramt3 *0.1;
double ramt4 = ramt3-amt4;
double amt5 = ramt4*0.1;
double ramt5 = ramt4- amt5;
int x = (int)ramt5 ;

Answer 1

shafiq your question appears unclear or as if this is a code coach solutions question. If this is the second, code coach solutions are for you to discover your strengths and weaknesses and to work with like a rubik's cube. If the community does it for you then what have you learned other than to have others do your work for you.

I encourage you to look at your code and to see if you missed something in the wording of the challenge itself.

Answer 2

Hi,BroFar.Yes, finally I did it.Problem was as follows:
You take a loan from a friend and need to calculate how much you will owe him after 6 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 6 months.

Sample Input:
20000

Sample Output:
10628

Here is the monthly payment schedule:
Month 1
Payment: 10% of 20000 = 2000
Remaining amount: 18000
,Month 2
Payment: 10% of 18000 = 1800
Remaining amount: 16200
Month 3:
Payment: 10% of 16200 = 1620
Remaining amount: 14580
Month 4:
Payment: 10% of 14580 = 1458
Remaining amount: 13122
Month 5:
Payment: 10% of 13122 = 1313
Remaining amount: 11809
Month 6:
Payment: 10% of 11809 = 1181
Remaining amount: 10628
My code is as follows:
double sum = (double) amount;
for(int i=1;i<=6;i++)
{
sum =Math.floor( sum-(sum*0.1));
}
int sum1 = (int)sum;
System.out.println(sum1);

Answer 3

Thanks to Benjamin.

Answer 4

You can just calculate amount * 0.9^6
Maybe the error is because you are rounding wrong. Int cast is like floor rounding

Answer 5

How is that post that you attached related to this?
