Sara's sister has 4 + 6 = 10 notebooks. After she loses 2, she will have: 10 - 2 = 8 notebooks.
The answer: 8
Reverse engineering the question: Sara's sister has 4 small notebooks in her closet. Last summer she ordered 6 more notebooks and then lost 2. How many notebooks does Sara's sister have now?
Reasoning and answer: Steve spends 24 / 3 = 8 hours sleeping. He spends 24 / 6 = 4 hours in school. He spends 24 / 12 = 2 hours making assignments. He spends 8 + 4 + 2 = 14 hours either sleeping, going to school, or making assignments. Hence, Steve spends 24 - 14 = 10 hours with his family.
The answer: 10
What was the question?
Question: Steve spends 1/3 of the day sleeping, 1/6 of the day in school, 1/12 of the day making assignments, and the rest of the day with his family. How many hours does Steve spend with his family in a day?
In her 2 albums, Beyonce releases 2 * 15 = 30 songs. In her next album, Beyonce releases 1 * 20 = 20 songs. Since each single is one song, Beyonce releases a total of 30 + 20 + 5 = 55 songs.
The answer: 55
Reverse engineering the question: Beyonce releases 5 different singles on iTunes. Then she releases 2 albums that each has 15 songs and 1 album that has 20 songs. How many songs has Beyonce released in total?
Reasoning and answer: First, we find what Tony's temperature is by adding his normal temperature of 95 to the increase in temperature from the sickness of 10, performing 95 + 10 = 105 degrees. Since the threshold for having a fever is 100, we subtract 100 from 105 to find out the answer, performing 105 - 100 = 5 degrees above a fever.
The answer: 5
What was the question?
Question: If Tony normally has a temperature of 95 degrees, and he comes down with a sickness that raises his temperature by 10 degrees, how many degrees above the threshold of fever is his temperature if a fever is anything over 100 degrees?
Coop:14 chickens. Run:14(2) = 28 chickens. Free Range:28(2) - 4 = 52 chickens.
The answer: 52
Reverse engineering the question: There are 14 chickens in the coop, and twice that many in the run. There is 4 less than double the number of chickens free ranging as in the run. How many chickens are free ranging?
If Pete walks on hands at 1 / 4 what Tracy can do 1 - handed cartwheels, then Tracy can do 1 - handed cartwheels at 2 * 4 = 8 miles per hour. Since Tracy does 1 - handed cartwheels twice the rate of Susan's forward walking, then Susan walks at 8 / 2 = 4 miles per hour. Pete walks backwards 3x faster than Susan walks forward, and thus Pete walks backwards at 4 * 3 = 12 miles per hour.
The answer: 12
Reverse engineering the question:
Pete walks backwards three times faster than Susan walks forwards, and Tracy does one-handed cartwheels twice as fast as Susan walks forwards. But Pete can walk on his hands only one quarter the speed that Tracy can do cartwheels. If Pete walks on his hands at 2 miles per hour, how fast can Pete walk backwards, in miles per hour?
