In the competition it was possible to get 0-5 points. In fact, 5 contestants of the 15 best contestants has earned 5 points or 4 points (which have won 10 contestants). The number of contestants who earned 3 points was the same as the number of contestants who did not get any points. Calculate the number of contestants if the average result achieved in the competition was actually 2 points.
