Task that i can't pass

[c06a8acb]

Hello. I am learning Python using pythontutor.ru website. There a task where i must write a program about bank deposit and it's profit 1 year later. I wrote a code, it gives right answer to all examples except 1. What can i do to make it right?

My code:

1 2 3 4 5 6 7

p = int(input()) x = int(input()) y = int(input()) kopeiki = ((p / 100) + 1) * ((x * 100) + y) answer_rubles = (kopeiki // 100) answer_kopeiki = int(kopeiki % 100) print(answer_rubles, answer_kopeiki)

Wrong answer: https://i.postimg.cc/pV1jxKYD/image.png
Link to a task: https://pythontutor.ru/lessons/int_and_f.../percents/

Thanks for reading.

Try this perhaps

1	r, k = divmod((100 + p) * (100 * x + y), 100)

Thank you for an answer. I really appreciate it.

But i am not allowed to use it.
Pythontutor is a course and (i think) we must use features that we were taught to use.
As long as i remember, there is no divmod.
We learnt only "if", "else", "*, /, //, %, **, +, -" and some "math" features that are listed here: https://pythontutor.ru/lessons/int_and_float/

Also, a task in English:

P - bank % for 1 year deposit
x - dollars
y - cents
How many dollars and cents are in a bank deposit after 1 year?

We must give an answer in this format: dollars, cents

"rubles" is a russian currency and "kopeiki" is russian "cents". There are 100 "kopeiki" in 1 ruble.

P.S. I will learn what "divmod" is.

If you wrote your own divmod it would look like this:

1 2	def mydivmod(a, b):     return (a // b, a % b)

Looking at your answer and the right answer, you are off by one kopek, low, on that one example only. Suggest this is a rounding error and that you are supposed to round up in that case?

If i will change the formula - it will affect other answers, and they will become wrong

[c06a8acb]

1 2 3 4 5 6 7 8

p = int(input()) x = int(input()) y = int(input()) all = x * 100 + y all1 = all + ((p / 100) * all) rubles = all1 // 100 kopeiki = all1 % 100 // 1 print(rubles, kopeiki)

This is the answer.
I didn't even know till now that you can write formulas without "int" or "float" or other.
And those "int" and "float" were messing the result all the way.
