The total number of eggs the family had is 3 * 12 = 36 eggs. If each adult received 3 eggs, the total number of eggs they got is 3 * 3 = 9 eggs. The children shared 36 - 9 = 27 eggs. Since each girl received an egg, the boys shared 27 - 7 = 20 eggs. If each boy received 1 egg more than each girl, each received 1 + 1 = 2 eggs. The boys received 20 eggs, and if each got 2 eggs, then 20 / 2 = 10 boys went on the trip.
The answer: 10
Reverse engineering the question: A family has three adults and children, both girls and boys. They went out for a family trip and prepared 3 dozen boiled eggs for the trip. Every adult got 3 eggs, and the boys each received 1 more egg than each girl since the girls had some snacks. How many boys went on the trip if the number of girls was 7 and each girl received an egg?


Reasoning and answer: First find the total amount of time he spends trying to get off the freeway: 2 hours * 4 = 8 hours. Then add the time he spends waiting in traffic to find the total time: 8 hours + 2 hours = 10 hours.
The answer: 10

Question: Martin spends 2 hours waiting in traffic, then four times that long trying to get off the freeway. How much time does he waste total?


Each chicken lays 3 eggs per day and there are 4 chickens 3 * 4 = 12. He will collect all the eggs after 3 days 12 * 3 = 36.
The answer: 36
Reverse engineering the question: Eric has a chicken farm with 4 chickens. His chickens lay 3 eggs each day. If Eric collects all the eggs after 3 days, then how many eggs will Eric have collected?


Reasoning and answer: Together, Betty and Bill picked 15 + 12 = 27 oranges. Frank picked 3 * 27 = 81 oranges. Frank planted 2 * 81 = 162 seeds in total, so there are 162 orange trees 20 years later. Philip can then pick 162 * 5 = 810 oranges.
The answer: 810
What was the question?
Question: Frank and his friends Betty and Bill went to their farm and picked oranges to eat. Betty picked 15 oranges and Bill picked 12 oranges. Frank picked three times the number that Betty and Bill picked combined. Frank then planted 2 seeds from each of his oranges into the ground and waited 20 years for each seed to turn into a beautiful orange tree. If each orange tree contains 5 oranges for Frank's son Philip to pick, how many oranges are there for Philip to pick in total?


First find the annual cost of food: $10 / day * 365 days = $3650. Then find how much she spends a week on lessons: $60 / lesson * 2 lessons = $120. Then multiply that weekly cost by the number of weeks per year to find the annual cost: $120 / week * 52 weeks / year = $6240. Then find the annual cost of the pasture: $500 / month * 12 months / year = $6000. Then add all the costs to find the total cost: $6000 + $6240 + $3650 = $15890.
The answer: 15890
Reverse engineering the question: Andrea buys herself a pony for her 30th birthday. She pays $500/month to rent a pasture for it, $10 a day for food, and $60/lesson for two lessons a week. How much does she spend on her pony in a year?


For the humans in the house, there are 5 * 2 = 10 legs. Javier has a total of 2 + 1 = 3 four - legged pets. For the pets in the house, there are 3 * 4 = 12 legs. There are a total of 10 + 12 = 22 legs.
The answer: 22
Reverse engineering the question:
Javier has a wife and 3 children. They have 2 dogs and 1 cat. Including Javier, how many legs are there in total in Javier’s household?
