Nick has made 20 * $10 = $200 from the chocolate oranges. This means he needs to raise another $1000 - $200 = $800. He needs to sell a total of $800 / $5 = 160 candy bars to reach his goal.
The answer: 160
Reverse engineering the question: Nick is trying to raise money for a charity. He is selling candy bars for $5. He is also selling chocolate oranges for $10. He wants to raise $1000. He only had 20 chocolate oranges that he sold out. How many candy bars does Nick need to sell to reach his goal?


Reasoning and answer: First find the number of pinecones eaten by reindeer: 20% * 2000 pinecones = 400 pine cones. Then find the total number of pinecones eaten by squirrels: 400 pine cones * 2 = 800 pine cones. Then subtract those two amounts to find the number of pinecones left: 2000 pinecones - 400 pine cones - 800 pine cones = 800 pinecones. Divide that number by 4 to find the number that are collected for fires: 800 pinecones / 4 = 200 pine cones. Then subtract that number from the 800 pinecones to find the total left on the ground: 800 pine cones - 200 pinecones = 600 pine cones.
The answer: 600
What was the question?
Question: There are 2000 pinecones on the ground. 20% are eaten by reindeer. Twice as many are eaten by squirrels as reindeer. 25% of the remainder are collected to make fires. How many pinecones are left?


He drives for a total of 2 * 2 = 4 hours. So he spends 4 * 2.5 = 10 hours at the beach. That means the total trip took 10 + 4 = 14 hours.
The answer: 14
Reverse engineering the question: Jake decides to go to the beach for a fun day. It is a 2-hour drive each way. He then spends 2.5 times at long at the beach as his total driving time. How much time does the trip take?


Reasoning and answer: Padma traded 2 + 15 of her cards = 17 cards. Robert traded 10 + 8 of his cards = 18 cards. In total, between both of them Padma and Robert traded 17 + 18 = 35 cards.
The answer: 35
What was the question?
Question: Padma is trading cards with Robert. Padma started with 75 cards and traded 2 or her valuable ones for 10 of Robert's cards. Robert started with 88 of his own cards and traded another 8 of his cards for 15 of Padma's cards. How many cards were traded between both Padma and Robert?


Casey can hula hoop 3 minutes less than Nancy so she can hula hoop for 10 - 3 = 7 minutes. Morgan can hula hoop three times as long as Casey, who can hula hoop for 7 minutes, so she can hula hoop for 3 * 7 = 21 minutes.
The answer: 21
Reverse engineering the question: Nancy can hula hoop for 10 minutes. Casey can hula hoop 3 minutes less than Nancy. Morgan can hula hoop three times as long as Casey. How long can Morgan hula hoop?


If Jane got 60 points and lost 20 points then the total number of points she accumulated in all the rounds was 60 + 20 = 80 points. If each round is awarded 10 points, then the number of rounds will be 80 / 10 = 8 rounds.
The answer: 8
Reverse engineering the question:
In a card game, you are awarded 10 points if you win one round. While playing, Jane ends up with 60 points. If she lost 20 points, then how many rounds did she play?
