Answer: the number of numbers is 1000.
The arithmetic mean of any number of numbers means the value of the total sum of these numbers divided by the value of this number. If we know the values of the arithmetic mean and the value of the sum of all numbers, then we can find the number of numbers by dividing the second by the first:
20.7 / 0.0207 = 1000.
