Correct Answer: 11
Solution :
The first 10 even numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20.
Average of a number = $\frac{\text{Sum of all the observations}}{{\text{Total number of observations}}}$
So, the average of these ten numbers
$=\frac{2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20}{10} = \frac{110}{10} = 11$
Hence, the correct answer is 11.
