There are 9 numbers, one number is randomly drawn each time, and the average of the remaining 8 numbers is calculated to obtain the following 9 different averages: 101, 102, 103, 104, 105, 106, 107, 108, 109, What is the average of these 9 numbers?
有9个数，每次任意抽去一个数，计算剩下8个数的平均数，得到如下9个不同的平均数：101、102、103、104、105、106、107、108、109，这9个数的平均数是多少．
<gadget id="calculator">101 + 102 + 103 + 104 + 105 + 106 + 107 + 108 + 109</gadget>
<output>945</output>

<gadget id="calculator">945 / 9</gadget>
<output>105</output>

<result>105</result>
