A team of street pavers was assigned the task of paving two parking lots one twice the size of the other. They worked for the first half of the day on the larger parking lot. Then the team split into two groups of equal number. The first group continued working on the larger parking lot and finished it by evening. The second group paved the smaller parking lot, but did not finish by evening. The next day one street-paver finished the smaller parking lot in a single day's work. How many street-pavers were on the original team?

Answer 1

Since they had to have finished over half of the parking lot by midday and the rest was finished by the end of the day with half the people they must have finished ⅔. And since the other half of the team was working on the smaller pavement ⅔ of the pavement got done since that is the equivalence of ⅓ of the larger pavement. Since 1 person did ⅓ of the smaller lot in one day then 2 people can finish ⅓ in half a day meaning that 4 people worked on the smaller pavement the second half of the day.
This means that the original team had 8 workers
