It takes 5 x 2 = 10 people to lift a truck. 5 x 6 = 30 people are needed to lift the cars. 10 x 3 = 30 people are needed to lift the trucks. Altogether, 30 + 30 = 60 people are needed.
The answer: 60
Reverse engineering the question: It takes 5 people to lift a car and twice as many people to lift a truck. How many people are needed to lift 6 cars and 3 trucks?


Reasoning and answer: Curry earned 12 x 2 = 24 points. Durant earned 9 x 2 = 18 points. Klay earned 12 / 2 = 6 points. Therefore, Golden States has a total of 12 + 24 + 9 + 18 + 6 = 69 points.
The answer: 69
What was the question?
Question: In the Golden State Team, each player earned points. Draymond earned 12 points, Curry earned twice the points as Draymond, Kelly earned 9, Durant earned twice the points as Kelly, Klay earned half the points as Draymond. How many points did the Golden States have in total?


There are 20 coins during the first hour. 30 coins are added during the second and third hours and 40 coins are added during the fourth hour. By the fourth hour there are 20 + 30 + 30 + 40 = 120 coins. The number of coins after giving 20 to her mother is 120 - 20 = 100.
The answer: 100
Reverse engineering the question: Tina decides to fill a jar with coins. In the first hour she puts in 20 coins. During the next two hours she puts in 30 coins each time. During the fourth hour she puts in 40 coins. During the fifth hour her mother asks to borrow some money so she takes 20 coins out. How many coins are left after the fifth hour?

The answer: 65
What was the question?
Question: Michael has 2 cats and 3 dogs. He needs to pay a friend to watch them, who charges $13 a night per animal. How much does Michael have to pay?


There are approximately 4 weeks in a month. The shop owner added 3 bikes every week for 4 weeks for a total addition of 3 * 4 = 12 bikes. The shop owner now has the original number of bikes + 12 bikes. She sold 18 bikes within the same time frame. She now has a total of 45 bikes which is: the original number of bikes + 12 - 18 = 45 bikes. The original number of bikes = 45 - 12 + 18 = 51 bikes.
The answer: 51
Reverse engineering the question: A bicycle shop owner adds 3 bikes to her stock every week. After 1 month, she had sold 18 bikes but still had 45 bikes in stock. How many bikes did she have originally?


Anya has 4 x 4 = 16 erasers. Thus, Anya has 16 - 4 = 12 more erasers than Andrea.
The answer: 12
Reverse engineering the question:
Anya has 4 times as many erasers as Andrea. If Andrea has 4 erasers, how many more erasers does Anya have than Andrea?
