How to calculate the exact number of participants from Moscow?
Thanks for the answer.

Answer 1

1) The interest calculation question is a high school level, what does IT and toaster have to do with it? Is this trolling?
2) The answer is fractional, 640.8099 => something is wrong with the condition
3) If the question is deeper than it looks at first glance, then add tags and specify the conditions.

Answer 2

1) 10319 * 6.21/100 = 641

Answer 3

The task, oddly enough, is not trivial.
What percentage is possible to round up to 6.21? From 6.205 to 6.215%.
The minimum number is 10319 * 6.205 / 100 = 640.29 The
maximum is 10319 * 6.215 / 100 = 641.32
The answer is unequivocal, 641 people.
If the rounding was more rough - for example, 6.2% - then it would be from 635 to 644.
