There are 25 boys and 21 girls in the tour group. There are three triple rooms for boys and girls, and the rest of them live in two rooms. How many girls need two people?
If boys and girls are divided into three triple rooms, then girls have 3*3 people =9 people, and there are 12 girls left, then six double rooms are needed.
If boys and girls are divided into three triple rooms, if girls only live in one room with 3 people and there are 18 people left, then nine double rooms are needed.
If girls live in two triple rooms *2=6, and there are 15 people left, it is not easy to allocate two rooms to pull.
Therefore, it is suggested that boys and girls can pull in a triple room separately, which is easy to arrange.
