The number of women in the group is 3 women / child * 30 children = 90 women. The number of men in the group is 2 men / woman * 90 women = 180 men. The total number of people in the group is 180 men + 90 women + 30 children = 300 people.
The answer: 300
Reverse engineering the question: A group of people contains men, women, and children. The number of men is twice the number of women, and the number of women is 3 times the number of children. If the number of children is 30, how many people does this group contain?

If the two expectant dogs gave birth to 10 puppies each, the total number of puppies Nalani had is 10 + 10 = 20. When they came of age, Nalani sold 3 / 4 of the dogs, a total of 3 / 4 * 20 = 15 dogs. If each dog sold for $200, Nalani received 15 * 200 = $3000 from the sale of the dogs.
The answer: 3000
Reverse engineering the question: Nalani had two female dogs that were expecting and after a month gave birth to 10 puppies each. She then sold 3/4 of the puppies after they came of age, each at $200. Calculate the total amount of money she received from the sale of the puppies.

From Monday to Friday, Iggy runs a total of 3 + 4 + 6 + 8 + 3 = 24 miles. Iggy runs for a total of 24 * 10 = 240 minutes. Since there are 60 minutes in an hour, Iggy runs for a total of 240 / 60 = 4 hours.
The answer: 4
Reverse engineering the question: Iggy is training for a marathon. On Monday, he runs 3 miles. On Tuesday, he runs 4 miles. On Wednesday, he runs 6 miles. On Thursday, he runs 8 miles. On Friday, he runs 3 miles. Iggy runs at a pace of 1 mile in 10 minutes. What is the total number of hours that Iggy spends running from Monday to Friday?

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
Reverse engineering the 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?
