[Question]A school has 15 classrooms. One-third of these classrooms have 30 desks in each classroom and the rest have 25 desks in each classroom. Only one student can sit at one desk. How many students can this school accommodate so that everyone has their own desk?
[Answer]One - third of the classrooms have 30 desks, so there are 1 / 3 * 15 = 5 classrooms like that. The rest, which means 15 - 5 = 10 classrooms, have 25 desks. One - third of the classrooms can fit 5 * 30 = 150 students. The rest can fit 10 * 25 = 250 students. So in total, the school can be filled with 150 + 250 = 400 students. The answer is 400.

[Question]A convenience store sold 100 bags of chips in a month. In the first week, 15 bags of chips were sold. In the second week, thrice as many bags of chips were sold. There was an equal number of chips sold in the third and fourth week. How many chips was each sold in the third and fourth week?
[Answer]In the second week, 15 x 3 = 45 bags of chips were sold. So there was a total of 45 + 15 = 60 bags of chips sold on the first and second week. Thus, a total of 100 - 60 = 40 bags of chips were sold on the third and fourth week. Therefore, 40 / 2 = 20 bags of chips were each sold on the third and fourth week. The answer is 20.

[Question]Kimberly went hiking and took a 4-liter bottle full of water with her. The first time she drank from it, she consumed a quarter of the water in the bottle. Later on, she drank 2/3rd of the remaining water. How much water is left in the bottle (in liters)?
[Answer]Her first drink consumed 1 / 4 * 4 = 1 liter of water. Thus there were 4 - 1 = 3 liters of water left in the bottle. Next, she drank 2 / 3 * 3 = 2 liters. Thus, there were 3 - 2 = 1 liters remaining. The answer is 1.

[Question]In one month in the Smith house, Kylie uses 3 bath towels, her 2 daughters use a total of 6 bath towels, and her husband uses a total of 3 bath towels.
