Felix's brother weighs 200 pounds because 600 / 3 = 200. Felix weighs 100 pounds because 200 / 2 = 100. Felix can lift 150 pounds because 100 x 1.5 = 150.
The answer: 150
Reverse engineering the question: Felix can lift off the ground 1.5 times more than he weighs. Felix's brother weighs twice as much as Felix and can lift three times his weight off the ground. If his brother can lift 600 pounds, how much can Felix lift off the ground?


Reasoning and answer: If one magazine costs $1, then 8 magazines cost 8 * $1 = $8. Let's define "x" as the cost of one chocolate bar. The cost of four chocolate bars is equal to the cost of 8 magazines and 4 * x = $8. Dividing each side by 4, we get the cost of one chocolate bar x = $2. Therefore, a dozen chocolate bars would cost 12 * $2 = $24.
The answer: 24
What was the question?
Question: The novelty shop on the Starship Conundrum sells magazines and chocolates. The cost of four chocolate bars is equal to the cost of 8 magazines. If one magazine costs $1, how much does a dozen chocolate bars cost, in dollars?


There are 3 hours * 60 minutes / hour = 180 minutes in 3 hours. You can paint 180 minutes / 20 houses / minute = 9 houses in 3 hours.
The answer: 9
Reverse engineering the question: If it takes 20 minutes to paint a house, how many houses can you paint in 3 hours?


Reasoning and answer: First figure out how long it takes to help one toddler: 4 minutes + 3 minutes = 7 minutes. Then multiply the time per toddler by the number of toddlers: 7 minutes / toddler * 2 toddlers = 14 minutes. Now add the time spent helping the toddlers to the time Jack spends on his own shoes: 14 minutes + 4 minutes = 18 minutes.
The answer: 18
What was the question?
Question: Jack needs to put his shoes on, then help both his toddlers tie their shoes. If it takes Jack 4 minutes to put his shoes on, and three minutes longer to help each toddler with their shoes, how long does it take them to get ready?


The nuts are $25.00 and he has a $5.00 coupon, so the nuts are on sale for $25 - $5 = $20.00. He eats 1 oz of nuts every evening and the bag has 40 oz of nuts, so it has 40 / 1 = 40 1 oz servings. The nuts cost $20.00 and there are 40 servings per bag, so his snack is $20 / 40 = $0.50 per serving.
The answer: 50
Reverse engineering the question: Hayden eats 1 oz of mixed nuts as an evening snack. He buys the bulk bag of mixed nuts that cost $25.00 a bag and holds 40 oz of mixed nuts. There is currently a $5.00 coupon for this item. How much will each serving of nuts cost, in cents, after the coupon is applied?


The cost of the hearing aids is $2500 * 2 = $5000. So insurance covers $5000 * .8 = $4000. That means it cost him $5000 - $4000 = $1000.
The answer: 1000
Reverse engineering the question:
John ends up damaging his hearing aids. He needs to replace both of them. They cost $2500 each. Insurance covers 80% of the cost. How much does he personally have to pay?
