Originally, there were 90*2/3=<<90*2/3=60>>60 in the cafeteria.

Originally, there were 90-60=<<90-60=30>>30 outside the cafeteria.

Then 30*1/3=<<30*1/3=10>>10 ran inside

The number of students inside the cafeteria grew by 10-3=<<10-3=7>>7.

There are now 60+7=<<60+7=67>>67 students in the cafeteria.

There are 90 students who have lunch during period 5. Today, two-thirds of the students sat in the cafeteria, while the remainder sat at the covered picnic tables outside. But some yellow-jackets were attracted to their food, and so one-third of the students outside jumped up and ran inside to the cafeteria, while 3 of the students in the cafeteria went outside to see what all the fuss was about. How many students are now in the cafeteria?
