Ответ:
There will be 16 people who are both writer and editor
Explanation:
We have given there are total of 100 people
So total = 100
There are 45 writers so,Writers = 45;
It is given that there are more than 38 editors so ,Editors > 38
Both = x;
Neither = 2x
We know that
Total = Writers + Editors - Both + Neither
100 = 45 + Editors - x + 2x
x = 55 - Editors
We want to maximize x, thus we should minimize Editors minimum possible value of Editors is 39, thus:
x = Both = 55 - 39 = 16.
