Question 1205541
<br>
(revised/corrected, to fix some typos....)<br>
None younger than 10, and 20 of them 10 or younger, means there are 20 who are 10 years old.<br>
Then 8 older than 10 makes a total of 28.<br>
The 6 that are older than 11 have already been counted, because they are older than 10.<br>
ANSWER: 28<br>
