"20 % completed" should be displayed.. How to do this calculation

Answer 1

Using Math.Round():

int percentComplete = (int)Math.Round((double)(100 * complete) / total); 

or manually rounding:

int percentComplete = (int)(0.5f + ((100f * complete) / total)); 

Answer 2

(current / maximum) * 100. In your case, (2 / 10) * 100.
