Question: In Professor Plum's biology class there are 40 students. Of those students, 80 percent have puppies. Of those who have puppies, 25% also have parrots. How many students have both puppies and parrots?
Answer: Step-by-step reasoning process: We start with the initial numbers of students, 40 and multiply that by .8 for 40 * 0.8 = 32 who own puppies. That the number of students with puppies, 32, and multiply that by .25 to find out how many own both puppies and parrots, 32 * 0.25 = 8 who own puppies and parrots. The answer is 8.
So the answer is 8.

Question: Since the 40th president launched his reelection campaign today, he has raised $10,000 in campaign funds. His friends raised 40% of this amount and his family raised 30% of the remaining amount. The rest of the funds are from his own savings for the election. How much did he save for the presidency?
Answer: Step-by-step reasoning process: The total amount of money raised from friends contribution is 40 / 100 * $10000 = $4000. Minus his friend's contribution, the 40th president has raised $10000 - $4000 = $6000. The family raised 30 / 100 * $6000 = $1800. If the family raised $1800, the savings the 40th president had for the campaign is $6000 - $1800 = $4200.
So the answer is 4200.

Question: A company was contracted to construct three buildings, with the second building being two times as tall as the first building. The third building had to be three times as tall as the combined height of the first and second buildings. If the first building was 600 feet, calculate the total height of the three buildings together.
Answer: Step-by-step reasoning process: The second building is two times as tall as the first building, a total of 600 * 2 = 1200 feet. The total height of the first and the second building is 1200 + 600 = 1800 feet. The third building is three times as tall as the combined height of the first and second buildings, which is 1800 * 3 = 5400 feet. Together, the three buildings have a total height of 5400 + 1800 = 7200 feet.
So the answer is 7200.
