Answer:
48 professors
Explanation:
First, add 11 + 6 = 17
Here is what I did after that,
136 / 17 = 8
I divided 136 by 17 because for every 11 lecturers there are 6 professors, and to get the total amount of how many times there are 6 professors and 11 lecturers.
After that, you would multiply 8 * 6, since there are 6 professors.
So, the answer that I got would be 48.
Hope this helps :)
