Come up with a question and reasoning that would justify [5] as the answer.
The question is: A pickup truck can fill 20 eight gallon water cans (each can filled three quarters of its capacity) in three hours. If each can is filled to full capacity instead, how long, in hours, will it take to fill 25 cans?
Reasoning: Each can is filled with 8 / 4 * 3 = 6 gallons of water. A total of 6 * 20 = 120 gallons of water is filled in 3 hours. In 1 hour, 120 / 3 = 40 gallons of water is filled. 25 full cans can hold 25 * 8 = 200 gallons of water. It will take 200 / 40 = 5 hours to fill 25 cans to full capacity.

Come up with a question and reasoning that would justify [364000] as the answer.
The question is: A cattle breeder owns 52 dairy cows. Each cow gives 1000 oz of milk per day. Calculate the amount of milk produced per week by the cows.
Reasoning: Per day, the amount of milk produced is 1000 * 52 = 52000 oz. Per week, the amount of milk produced is 52000 * 7 = 364000 oz.

Come up with a question and reasoning that would justify [520000] as the answer.

The question is: John sends his son to prep school. It cost $20,000 per semester. There are 2 semesters in the year. How much does it cost to send the kid to 13 years of school?
Reasoning: It cost 20000 * 2 = $40,000 a year. So it cost 40,000 * 13 = $520,000.
