One hour contains 60 minutes so 2 hours contain 60 * 2 = 120 minutes. Alpha Epsilon's running time is 30 minutes less than that of Millennium (which runs for 120 minutes) hence 120 - 30 = 90 minutes. Beast of War: Armoured Command runs for 10 minutes more than Alpha Epsilon hence 90 + 10 = 100 minutes.
The answer: 100
Reverse engineering the question: The running time of Beast of War: Armoured Command is 10 minutes longer than that of Alpha Epsilon, which is 30 minutes shorter than that of Millennium. If Millennium runs for 2 hours, what is the running time of Beast of War: Armoured Command in minutes?


Reasoning and answer: Each class uses 200 x 5 = 1000 sheets of paper in a week. Thus, there are 9000 / 1000 = 9 classes in the school.
The answer: 9
What was the question?
Question: Each class uses 200 sheets of paper per day. The school uses a total of 9000 sheets of paper every week. If there are 5 days of school days, how many classes are there in the school?


The fisherman earns $3 x 8 = $24 per day on Red snappers. He earns $2 x 14 = $28 per day on Tunas. Therefore, the total amount he earns is $24 + $28 = $52.
The answer: 52
Reverse engineering the question: The fisherman gets 8 Red snappers and 14 Tunas every day. If a Red snapper costs $3 and a Tuna costs $2, how much does he earn every day?


Reasoning and answer: If the bananas Charles cooked were 3 times the number of pears he picked, then Charles cooked 3 * 50 = 150 bananas. Since all the dishes that Sandrine washed were 10 more than the number of bananas Charles cooked, Sandrine washed 150 + 10 = 160 dishes.
The answer: 160
What was the question?
Question: The number of dishes Sandrine washed was 10 more than the number of bananas Charles cooked. Also, the number of bananas Charles cooked was 3 times the number of pears he picked. If Charles picked 50 pears, how many dishes did Sandrine wash?


First find how many burrs are caught in the dog's fur: 12 burrs * 6 ticks / burr = 72 ticks. Then add the number of burrs to find the total number objects: 72 objects + 12 objects = 84 objects.
The answer: 84
Reverse engineering the question: Andrew's dog has 12 burrs and six times as many ticks as burrs. How many foreign objects total are caught in the dog's fur?


Mary fed Luna 1 + 1 = 2 cups of kibble. Frank fed Luna 1 - cup plus twice 1 - cup, or 1 + 2 = 3 cups of kibble. In total, they fed Luna 2 + 3 = 5 cups of kibble. Thus, if the new bag held 12 cups of kibble, the next morning, 12 - 5 = 7 cups of kibble remained in the bag.
The answer: 7
Reverse engineering the question:
Luna, the poodle, is supposed to eat 2 cups of kibble every day. But Luna's master, Mary, and her husband, Frank, sometimes feed Luna too much kibble. One day, starting with a new, 12-cup bag of kibble, Mary gave Luna 1 cup of kibble in the morning and 1 cup of kibble in the evening, But on the same day, Frank also gave Luna 1 cup of kibble in the afternoon and twice as much in the late evening as he had given Luna in the afternoon. The next morning, how many cups of kibble will Mary find remaining in the bag?
