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: Edward the plumber is replacing a pipe in a bathroom wall. He needs to use 40 feet of copper pipe to complete the job. For every 5 feet of pipe, Edward must use one tightening bolt, and for every bolt, he uses two washers. He buys a bag of 20 washers for the job. After he completes the bathroom job, how many washers will be remaining in the bag?
A: If Edward needs to use 1 bolt per every five feet of piping, then for a job requiring 40 - feet of piping, he will use 40 / 5 = 8 tightening bolts. If for every 1 bolt he uses two washers, then he will need 8 * 2 = 16 washers to complete the job. if he buys a bag containing 20 washers, and removes 16, he will have 20 - 16 = 4 washers remaining in the bag. The answer is 4.
Question: Angela is a bike messenger in New York. She needs to deliver 8 times as many packages as meals. If she needs to deliver 27 meals and packages combined, how many meals does she deliver?
Answer: Let p be the number of packages Angela delivers and m be the number of meals. We know that p + m = 27 and p = 8m. Substituting the second equation into the first equation, we get 8m + m = 27. Combining like terms, we get 9m = 27. Dividing both sides by 9, we get m = 3. The answer is 3.
[Question]A farmer is selling ducks and chickens at the market. He sells ducks for $10 and chickens for $8. He sells 5 chickens and some ducks. He then spends half his earnings on a new wheelbarrow. After buying it, someone sees it and agrees to pay the farmer double what the farmer paid and the farmer earns another $60. How many ducks did the farmer sell?
[Answer]The wheelbarrow cost $30 because 60 / 2 = 30. The farmer earned $60 from selling fowl because 30 / (1 / 2) = 60. The farmer earned $40 selling chickens because 5 x 8 = 40. The farmer earned $20 selling ducks because 60 - 40 = 20. The farmer sold 2 ducks because 20 / 10 = 2. The answer is 2.
