Marina = 4.5 pounds = 72 ounces. Lazlo = 4 pounds - 6 ounces = 58 ounces. 72 - 58 = 14 ounces. Marina had 14 more ounces of fudge than Lazlo.
The answer: 14
Reverse engineering the question: Marina had 4.5 pounds of fudge. Lazlo had 6 ounces less than 4 pounds of fudge. How many more ounces of fudge did Marina have than Lazlo?


Reasoning and answer: There are 70 / 7 = 10 weeks in 70 days. So he takes 10 * 3 = 30 naps. That means he naps for 30 * 2 = 60 hours.
The answer: 60
What was the question?
Question: John takes 3 naps a week. Each nap is 2 hours long. In 70 days how many hours of naps does he take?


In the first part of her trip, Diana will cover 2 hours * 3 mph = 6 miles. In the second part of her trip, Diana will need to cover an additional 10 miles - 6 miles = 4 miles. To cover 4 miles * 1 mph = will take Diana 4 hours. Total biking time to get home for Diana will be 2 hours + 4 hours = 6 hours.
The answer: 6
Reverse engineering the question: Diana needs to bike 10 miles to get home. She can bike 3 mph for two hours before she gets tired, and she can bike 1 mph until she gets home. How long will it take Diana to get home?


Reasoning and answer: There are 60 minutes in an hour, and 60 seconds in a minute so there are 60 * 60 = 3600 seconds in an hour. The device records data every 5 seconds so there will be 3600 / 5 = 720 instances of data in an hour.
The answer: 720
What was the question?
Question: Josh has a device that automatically records the temperature in his lab every 5 seconds. To perform an analysis of environmental conditions, Josh lets the device record data for one hour. How many instances of data will the device record?


The dragon stole 2 * 3 = 6 of the king’s crown jewels. The dragon owned 6 * 3 = 18 jewels before the theft. Thus, the dragon owned 18 + 6 = 24 jewels in the end.
The answer: 24
Reverse engineering the question: A dragon hoards jewels and gold in its cave. A jealous king snuck in and stole three prize jewels. The dragon burned him to a crisp and stole back its jewels, along with twice as many of the king’s crown jewels from his crown that melted in the dragon’s fire. The new jewels were a third of the number of jewels the dragon had owned before. How many jewels did the dragon own in the end?


If on the return journey to its home, the alligator took 2 more hours than it took to travel to the Nile Delta, Paul took 4 + 2 = 6 hours to travel back to its home. The total time Paul took to travel from its home to the Nile Delta and back is 6 + 4 = 10. On his return journey, Paul traveled with six other alligators, and since each alligator traveled for six hours up the Nile to their home, they took a total of 6 * 6 = 36 hours to do so. Together with Paul, all the alligators took 10 + 36 = 46 hours traveling between Nile Delta and up the Nile.
The answer: 46
Reverse engineering the question:
It took an alligator named Paul 4 hours to walk from his home at the River Nile to the Nile Delta. On the return journey, Paul traveled with six other alligators, the journey taking 2 more hours than Paul took to walk to the Nile Delta, to reach their home at the River Nile. What's the combined time the alligators walked?
