Q: In Mary's class, there are 25 students. Their teacher told them they could pay $50 each to finance a big science project that they and their society would benefit greatly from. They all paid the full amount except for 4 students, who paid half. How much was the class able to gather together?
A: The original amount is $50 so half is $50 / 2 = $25. 4 students paid half ($25) for a total of 4 * $25 = $100. There are 25 - 4 = 21 students left. 21 students paid the full amount ($50) for a total of 21 * $50 = $1050. They were able to gather a total of $100 + $1050 = $1150. The answer is 1150.

[Question]In the city, there is a block of flats. This block has 12 floors. Half of the floors have 6 apartments and the other half have 5 apartments. One apartment can accommodate a maximum of 4 residents. What is the maximum number of residents that can live in this block of flats?
[Answer]Half of the floors have different numbers of apartments. Half the number of floors is 12 floors / 2 = 6 floors. One half of the block consists of 6 floors * 6 apartments / floor = 36 apartments. And the other half consists of 6 floors * 5 apartments / floor = 30 apartments. There are 30 + 36 = 66 apartments on all floors in the block. All the apartments can therefore accommodate 66 apartments * 4 residents / apartment = 264 residents. The answer is 264.
Q: Arwen and Elrond picked some flowers. Arwen was able to get 20 tulips and Elrond was able to get twice as many tulips as Arwen did. How many tulips were they able to get in total?

Q: A van is delivering 180 bottles of drinks to a neighborhood, and each bottle contains either cider or beer or a mixture of two. Out of the 180 bottles, 40 contain only cider, 80 contain only beer, and the rest are a mixture of the two drinks. If the delivery man gives half the number of each bottle of drink to the first house, how many bottles does the first house get?
A:
The total number of bottles containing cider or beer is 40 + 80 = 120. If the number of bottles in the van was 180, then 180 - 120 = 60 contains a mixture of the two drinks. At the first house, the delivery man dropped 1 / 2 * 40 = 20 bottles. There were also 1 / 2 * 80 = 40 bottles of beer that the delivery man gave to the first house. Together, the first house received 40 + 20 = 60 bottles of cider and beer. The total number of bottles that had a mixture of the two drinks that were dropped at the first house is 1 / 2 * 60 = 30. The first house got 60 + 30 = 90 bottles of all types of drinks. The answer is 90.
