The factory due to shortages will produce 200 - 50 = 150 cars. Due to the pandemic, they will now produce 150 / 2 = 75 cars. The company will have to manufacture 75 * 5 = 375 doors.
The answer: 375
Reverse engineering the question: A factory manufactures cars with 5 doors. The factory was planning to produce 200 cars but due to metal shortages, they decreased the production by 50 cars. Due to a pandemic, they also had to cut production by another 50%. How many doors will the factory produce?


Reasoning and answer: He bought 12 - 3 - 2 = 7 blue notebooks. He paid 3 * $4 = $12 for red notebooks. He paid 2 * $2 = $4 for green notebooks. He spent $37 - $12 - $4 = $21 on blue notebooks. Each blue notebook costs $21 / 7 = $3.
The answer: 3
What was the question?
Question: Mike spent 37 dollars on notebooks. He bought a total of 12 notebooks. He bought 3 red notebooks at 4 dollars each, 2 green notebooks at 2 dollars each, and the rest were blue notebooks. How much does each blue notebook cost?


If Alexis has four times the combined number of mangoes Dilan and Ashley has, then they both have 60 mangoes / 4 = 15 mangoes. The total number of mangoes for all of them is 15 mangoes + 60 mangoes = 75 mangoes.
The answer: 75
Reverse engineering the question: Alexis has four times as many mangoes as Dilan and Ashley combined. If Alexis has 60 mangoes, how many mangoes does all of them have combined?


Reasoning and answer: Alison gave Anna 1 / 2 * 28 = 28 / 2 = 14 stamps. Adding Alison’s stamps to Anna’s collection means Anna has 14 + 37 = 51 stamps. Then Anna traded Jeff 2 stamps, so she had 51 - 2 = 49 stamps. Anna got 1 stamp back in the trade, so she had 49 + 1 = 50 stamps in the end.
The answer: 50
What was the question?
Question: Anna, Alison, and Jeff collect stamps. Anna had 37 stamps in her collection, Alison had 28 stamps in her collection, and Jeff had 31 stamps in his collection. Alison gave Anna half of her collection in exchange for a novel, and then Anna traded Jeff two bluebird stamps for one mountain stamp. How many stamps did Anna have in the end?


Grace will have 10 x 10 = 100 pennies from her dimes. She will have 10 x 5 = 50 pennies from her nickels. Therefore, she will have a total of 100 + 50 = 150 pennies.
The answer: 150
Reverse engineering the question: A dime has the same value as 10 pennies and a nickel has the same value as 5 pennies. How many pennies will Grace have by exchanging her 10 dimes and 10 nickels?


The price of a personal computer is $300 + $500 = $800. The price of an advanced tablet would be $300 + $800 = $1100. To buy each of these products, you would have to pay $300 + $800 + $1100 = $2200.
The answer: 2200
Reverse engineering the question:
An electronic shop offers smartphones for $300 each, personal computers for $500 more than smartphones, and advanced tablets for the sum of the prices of a smartphone and personal computer. How much do you have to pay to buy one of each of the three mentioned products?
