Answer the following 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?
Step-by-step reasoning process: 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.

Answer the following question.
James watched 2 episodes of Jeopardy and 2 episodes of Wheel of Fortune. Jeopardy is 20 minutes and Wheel of Fortune is twice as long. How many hours did he watch TV?
Step-by-step reasoning process: He watched 2 * 20 = 40 minutes of Jeopardy. Wheel of Fortune is 2 * 20 = 40 minutes each. So he watched it for 40 * 2 = 80 minutes. So he watched 40 + 80 = 120 minutes of TV. That means he watched 120 / 60 = 2 hours of TV.
The answer is 2.

Answer the following question.
Meena bakes 5 dozen cookies for the school’s bake sale. She sells 2 dozen cookies to her biology teacher, Mr. Stone. Her friend Brock buys 7 cookies, and her friend Katy buys twice as many as Brock. How many cookies does Meena have left?
Step-by-step reasoning process: Meena bakes a total of 5 x 12 = 60 cookies. Mr. Stone buys 2 x 12 = 24 cookies. Brock buys 7 cookies, so Katy buys 2 x 7 = 14 cookies. Meena sells a total of 24 + 7 + 14 = 45 cookies. She has 60 - 45 = 15 cookies left.
The answer is 15.
