Reasoning and answer: Brian begins by watching a 4 - minute video, and since the second video is twice as long that means the second video is 4 * 2 = 8 minutes. The first two videos combined therefore for a 4 + 8 = 12 minute run time. Since the third video is twice as long as the first two videos put together, that means it is 12 * 2 = 24 minutes in length. The total length of time spent is therefore 24 + 12 = 36 minutes.
The answer: 36

Question: Brian loves watching animal videos online. He watches a 4-minute video of cats. He then watches a video twice as long as the cat video involving dogs. He finishes up his video watching for the day by watching a video on gorillas that's twice as long as the previous two videos combined. How many minutes does Brian spend watching animal videos?


Since Agate has 30 precious stones and Olivine has 5 more precious stones, then Olivine has 30 + 5 = 35 precious stones. The total number of stones Olivine and Agate has is 35 + 30 = 65. Diamond has 11 more precious stones than Olivine, who has 35 stones, meaning Diamond has 35 + 11 = 46 precious stones. In total, they all have 65 + 46 = 111 precious stones.
The answer: 111
Reverse engineering the question: If olivine has 5 more precious stones than agate and diamond has 11 more precious stones than olivine, how many precious stones do they have together if agate has 30 precious stones?


Reasoning and answer: The 3 - year - old dog ages 7 years to one human year so he will technically be 3 * 7 = 21 years old in dog years. Max's dog will be 21 when Max turns 3 so the age difference is 21 - 3 = 18.
The answer: 18

Question: For every 1 year a human ages, a dog ages 7 years. When Max is 3, how much older, in dog years, will his 3-year-old dog be?


The second pair of shoes was 50 / 100 * 22 = $11 more expensive. That means that the second pair's price was 22 + 11 = $33. So for both pairs of shoes, Nina paid 33 + 22 = $55.
The answer: 55
Reverse engineering the question: Nina has two pairs of shoes. She bought one of them for $22, and the second one was 50% more expensive. How much did Nina pay for both pairs of shoes?


Reasoning and answer: The elephant weighs 3 * 2000 = 6000 pounds. The donkey weighs 6000 * .9 = 5400 pounds less. So the donkey weighs 6000 - 5400 = 600 pounds. That means the combined weight is 600 + 6000 = 6600 pounds.
The answer: 6600

Question: John has a donkey and an elephant. The elephant weighs 3 tons (a ton is 2000 pounds). The donkey weighs 90% less. What is their combined weight in pounds?


Reasoning and answer: The age of Robert now is 30 - 2 = 28 years old. So, Patrick is 28 / 2 = 14 years old.
The answer: 14
What was the question?
Question:
