There’s 3 lines into a building: red, green and blue. Every person in line has purchased a non refundable ticket for a tour. The goal is for as many tours as possible for all participants.
Red line has 70 people, green line 20 people and blue line 10 people. Two people at a time must enter the building with two from each of the other lines, creating groups of 6. Once the tour is completed, all colors can return to their color line to rejoin the group.
At the end of the day, groups can only go as fast as the number of blue liners. So 10 blues, 10 greens, and 10 reds enter together. When they come back from the tour, all 10 blue get to go again, the 10 greens who were waiting now get to go, and 10 new reds get to go. Blue line has completed the tour, green too. Meanwhile 50 red liners are still waiting to go through 1 time, when blue line returns for their third trip, and half of green is about to get their second.
Now here’s where this becomes important.
If blue line gets tired of the tour and leaves, nobody can tour anymore.
Likewise if green line gets bored and half of them leave, there’s still 60 reds in waiting at time.
There’s only 2 ways to give red line a faster tour-
Either make every line red line
OR
Make green line and blue line more appealing.
This isn’t about color lines or tours.
