This many baby turtles are in the ocean: 42 / 3 = 14 turtles. This many baby turtles are still on the sand: 42 - 14 = 28 turtles.
The answer: 28
Reverse engineering the question: A total of 42 baby sea turtles hatched and are headed to the ocean. One-third of them got swept to the sea by a wave. How many are still on the sand?


Reasoning and answer: Joyce's new land is 10 times larger than her old 2 - acre property, for a total of 2 * 10 = 20 acres of land. One acre is not suitable for farming, leaving her with 20 - 1 = 19 acres of land suitable for farming.
The answer: 19
What was the question?
Question: Joyce moved to the countryside because she needed more farmland to grow her vegetables. Her new property is 10 times larger than her previous property, but her new land has a 1-acre pond on it where she cannot grow vegetables. If her previous property was 2 acres, how many acres of land does she now own that are suitable for growing vegetables?


Let X be the price of the borrowed amount. The interest is X * .12 = $1500. So the borrowed amount is X = $1500 / .12 = $12500.
The answer: 12500
Reverse engineering the question: A person borrowed an amount of money for a year at an interest rate of 12%. If the total interest is $1500, what was the original borrowed amount?


Reasoning and answer: The distance between Arizona and New York is 2,000 miles by plane. The distance between Arizona and New York is 40% greater by car, which is 40% * 2,000 = 800 miles. This results in a total of 2,000 + 800 = 2,800 miles between Arizona and New York by car. If Missouri is in the middle of the way between Arizona and New York, someone would drive half of the distance to go from Missouri to New York, which is 2,800 / 2 = 1,400.
The answer: 1400
What was the question?
Question: The distance between Arizona and New York is around 2,000 miles by plane. The distance between the 2 different US states increases by 40% if someone decides to drive instead of flying. Missouri is midway between Arizona and New York. How far away is Missouri from New York if someone decides to go by car?


If Vermont found 12 ads on the first web page and twice as many ads on the second web page as the first web page, he found 12 * 2 = 24 ads on the second web page. The first and the second web page had a total of 12 + 24 = 36. Vermont also found 24 more ads on the third web page than the second web page, a total of 24 + 24 = 48 ads. The first three web pages had 48 + 36 = 84 ads. The fourth web page had 3 / 4 times as many ads as the second web page, a total of 3 / 4 * 24 = 18 ads. In all the web pages Vermont opened, he found 84 + 18 = 102 ads. If he clicked on 2 / 3 of them, he clicked on 2 / 3 * 102 = 68 ads.
The answer: 68
Reverse engineering the question: Vermont opened up 4 web pages on his web browser and found 12 ads on the first web page and twice as many ads on the second web page as the first web page. When he opened the third web page, he found 24 more ads than the number of ads on the second web page. If the fourth web page had 3/4 times as many ads as the second web page, calculate the total number of ads Vermont clicked on if he clicked on 2/3 of them.


The factory creates 300 gummy bears a minute, which means it produces 300 / 50 = 6 packets of gummy bears per minute. It would take 240 / 6 = 40 minutes to manufacture enough gummy bears to fill 240 packets.
The answer: 40
Reverse engineering the question:
The gummy bear factory manufactures 300 gummy bears a minute. Each packet of gummy bears has 50 gummy bears inside. How long would it take for the factory to manufacture enough gummy bears to fill 240 packets, in minutes?
