[Question]A class has 60 students. The number of students who bring their lunch is thrice the number of those who eat in the school cafeteria. The rest of the students don't eat lunch. If 10 students eat in the school cafeteria, how many don't eat lunch?
[Answer]Multiplying the number of students eating at the cafeteria by three means that 3 * 10 = 30 students bring lunch. The total number of students that eat lunch is 10 + 30 = 40 students. Since the class has 60 students, those who don't eat lunch are 60 - 40 = 20 students. The answer is 20.

Question: Team Soccer Stars plays in a soccer league. They played a total of 20 games, and won 14 games, lost 2, and drew the rest of the matches. They earn 3 points for a win, 1 point for a draw, and nothing for a loss. How many points did they have at the end of the season?
Answer: Soccer Stars won and lost a total of 14 + 2 = 16 games. This means they drew 20 - 16 = 4 games. The total points from the wins are 14 * 3 = 42 points. The total points from draws are 4 * 1 = 4 points. The total points from the losses are 2 * 0 = 0 points. They had 42 + 4 + 0 = 46 points when the season ended. The answer is 46.

Q: Angeli had 90 assorted candies. One-third of the candies were lollipops and the rest were candy canes. She then shared the lollipops equally among the boys such that each boy received 3. She then shared the candy canes equally among the girls such that each received 2. How many boys and girls were given altogether?
A: There were 90 / 3 = 30 lollipops. So, 90 - 30 = 60 are candy canes. Each boy received 3 lollipops, so there were 30 / 3 = 10 boys. Each girl received 2 candy canes, so there were 60 / 2 = 30 girls. Altogether, there were 10 + 30 = 40 boys and girls. The answer is 40.
