6 days

Explanation:

First, we need to figure out how many portions are being used overall before they leave
#200xx31=6200#
Now, since 200 use it for 27 days, we can subtract that.
#6200-(200xx27)=800#
Now the 120 leave.
#200-120=80#
Since 800 portions remain, we can do #800/80=10#
However, there are still 4 planned days left. As such, we need to take that from our current answer
#10-4=6#
