A pound of cream cheese cost $10 / 2 = $5. A pack of cold cuts cost $10 x 2 = $20. Jasper spent $10 + $5 + $20 = $35 on the ingredients.
The answer: 35
Reverse engineering the question: Jasper will serve charcuterie at his dinner party. He buys 2 pounds of cheddar cheese for $10, a pound of cream cheese that cost half the price of the cheddar cheese, and a pack of cold cuts that cost twice the price of the cheddar cheese. How much does he spend on the ingredients?


Reasoning and answer: The total ratio for the number of cats and dogs that Heloise has is 10 + 17 = 27. From the ratios, the fraction representing the number of dogs is 10 / 27, and this represents 10 / 27 * 189 = 70 dogs. If Heloise gives 10 of her dogs to Janet, she remains with 70 - 10 = 60 dogs.
The answer: 60
What was the question?
Question: Heloise has dogs and cats in the ratio of 10:17, with the total number of pets being 189. If she gives 10 dogs to her friend Janet, how many dogs does she remain with altogether?


In this house, there are 16 * 25 / 100 = 4 black cats. If there are two white cats, that means that there are 16 - 4 - 2 = 10 grey cats in this house.
The answer: 10
Reverse engineering the question: In a house, there are 16 cats. Two of them are white, and 25% of them are black. The rest of the cats are grey. How many grey cats are in this house?


Reasoning and answer: Sasha completes 15 questions / hour * 2 hours = 30 questions. This means there are still 60 questions – 30 questions = 30 questions left to complete.
The answer: 30
What was the question?
Question: Sasha can complete 15 questions an hour. If she has 60 questions to complete and she works for 2 hours, how many questions does she still need to complete?


Brian sold houses for 157,000 + 499,000 + 125,000 = $781,000 in total. Brian's commission was 781,000 * 0.02 = $15,620.
The answer: 15620
Reverse engineering the question: Brian is a real estate agent. He makes a 2% commission on each sale. During June, he sold three houses. The houses sold for $157,000, $499,000, and $125,000. What was Brian’s total commission on these three sales?


Jolyn is 2 + 5 = 7 months older than Aivo. Since Leon is 2 months older than Aivo, then Jolyn is 7 - 2 = 5 months older than Leon.
The answer: 5
Reverse engineering the question:
Four classmates were comparing their ages based on their birth month. They found out that Jolyn is 2 months older than Therese while Therese is 5 months older than Aivo. Then, Leon is 2 months older than Aivo. How much older in months is Jolyn than Leon?
