The first two studios have 110 + 135 = 245 students. The remaining studio has 376 – 245 = 131 students.
The answer: 131
Reverse engineering the question: Three local dance studios have 376 students. The first two have 110 and 135 students. How many students does the third studio have?


Reasoning and answer: The second laptop costs $500 * 3 = $1500. Adam needs to spend $1500 + $500 = $2000 for both.
The answer: 2000
What was the question?
Question: Adam needs a new laptop and has two choices. The first laptop is $500, and the second laptop is 3 times as costly as the first laptop. How much would Adam have to spend if he decides to buy both?


Nathalie's score is 4 + 3 = 7. And the total points of Nathalie and Lizzie when combined is 7 + 4 = 11. So, the total score of Aimee is 11 x 2 = 22. Lizzie, Nathalie, and Aimee's total score is 22 + 11 = 33. Therefore, their teammates were able to score 50 - 33 = 17.
The answer: 17
Reverse engineering the question: In a Volleyball competition, Lizzie was able to score 4 points. Nathalie's score is 3 more than Lizzie's score and Aimee's score is twice the score of Lizzie and Nathalie combined. The rest of the points were made by their teammates. If the whole team was able to score 50 points, how many points did their teammates make?


Reasoning and answer: If Tenisha has 40 dogs, the number of female dogs is 60 / 100 * 40 = 24. 3 / 4 of the females give birth, meaning 3 / 4 * 24 = 18 female dogs gives birth to puppies. Since each dog that gave birth had 10 puppies, the number of puppies that were born is 18 * 10 = 180. After donating 130 puppies to the church, Tenisha remained with 180 - 130 = 50 puppies.
The answer: 50
What was the question?
Question: Tenisha had 40 dogs that she kept at home as pets. If 60% of them are female, and 3/4 of the female gives birth to 10 puppies each, calculate the total number of puppies that Tenisha remains with after donating 130 puppies to the church.


He knows 800 * .2 = 160 words. So he needs to learn 800 - 160 = 640 words. That means he needs to learn 640 / 40 = 16 words per day.
The answer: 16
Reverse engineering the question: Bo is learning words for the GRE. He got 800 flashcards. He knew 20% of the words on them. He has 40 days to learn the rest. How many words does he need to learn a day?


If Kimiko is 28, Omi is 2 * 28 years = 56 years old. Arlette is 3 / 4 * 28 years = 21 years old. If you add up their ages, it sums to 21 years + 56 years + 28 years = 105 years. The average age for the three is 105 years / 3 people = 35 years / person.
The answer: 35
Reverse engineering the question:
Omi is twice as old as Kimiko. Arlette is 3/4 times as old as Kimiko. If Kimiko is 28 years old, calculate the average age of the three?
