In the blue basket, there are 12 bananas + 4 apples = 16 fruits. The red basket holds half of this so there are 16 fruits in the blue basket / 2 = 8 fruits in the red basket.
The answer: 8
Reverse engineering the question: There are 12 bananas and 4 apples in the blue basket. The red basket holds half as many fruits as the blue basket. How many fruits are in the red basket?


Reasoning and answer: First find how many dogs get adopted each month by multiplying the number of dogs by their chance of getting adopted: 30 dogs * 50% = 15 dogs. Then do the same thing for the cats: 28 cats * 25% = 7 cats. And do the same thing for the lizards: 20 lizards * 20% = 4 lizards. Now add up the number of each kind of pet to find the initial total number of pets: 30 dogs + 28 cats + 20 lizards = 78 pets. Now subtract all the pets that get adopted in one month from the initial number of pets: 78 pets - 15 dogs - 7 cats - 4 lizards = 52 pets. Now add the extra 13 pets the shelter takes in that month to find the final number of pets: 52 pets + 13 pets = 65 pets.
The answer: 65

Question: Karen works at an animal shelter with 30 dogs, 28 cats, and 20 lizards. Every month, 50% of the dogs are adopted, 25% of the cats are adopted, and 20% of lizards are adopted. If the shelter takes in 13 new pets a month, how many pets are there after one month?


He cuts his grass 4 - 2 = 2 inches. So he gets it cut every 2 / .5 = 4 months. That means he gets it cut 12 / 4 = 3 times a year. So he pays 100 * 3 = $300 per year.
The answer: 300
Reverse engineering the question: John cuts his grass to 2 inches. It grows .5 inches per month. When it gets to 4 inches he cuts it back down to 2 inches. It cost $100 to get his grass cut. How much does he pay per year?


Reasoning and answer: Tom ideally wants to sleep 8 hours a night for 7 days, 8 x 7 = 56 hours sleep total for the week. Tom has actually only slept 5 hours each weeknight, 5 x 5 = 25 hours of sleep. Tom has only slept 6 hours each night on the weekend, 6 x 2 = 12 hours of sleep. Total, Tom has gotten 25 + 12 hours = 37 hours sleep. The difference between how many hours Tom would like to sleep, 56, and how many hours he's actually slept, 37, is 56 - 37 = 19 hours of sleep that Tom is behind on.
The answer: 19
What was the question?
Question: Tom hasn't been sleeping well lately. He figures he has been getting about 5 hours of sleep each weeknight and 6 hours each night on the weekend. If Tom would ideally like to get 8 hours of sleep each night on both weeknights and weekends, how many hours of sleep is Tom behind on from the last week?


Jack had 13 more than 8 notebooks for a total of 13 + 8 = 21 notebooks. He gave 5 notebooks to Paula so he has 21 - 5 = 16 notebooks left. He gave another 6 to Mike so he has 16 - 6 = 10 notebooks left.
The answer: 10
Reverse engineering the question: Jack says he has 13 more notebooks in his bag than Gerald. Jack gives 5 notebooks to Paula and 6 notebooks to Mike. If Gerald has 8 notebooks, how many notebooks does Jack have left?


The 15 families own 15x2 = 30 dogs. The 20 families own 20x1 = 20 dogs. There are 50 - 15 - 20 = 15 cat owners. The remaining families own 15x2 = 30 cats. There are 30 + 20 + 30 = 80 dogs and cats in the village.
The answer: 80
Reverse engineering the question:
In a community of 50 families, 15 families own 2 dogs, 20 families own 1 dog, while the remaining families own 2 cats each. How many dogs and cats are there in all?
