Reasoning and answer: The total number of people transported in the first trip is 100 one way + 60 on the return trip = 160 people. If the train made three more round trips that day carrying the same number of passengers in each trip as the first, it carried a total of 3 * 160 = 480 in all three round trips. In total, the train carried 160 + 480 = 640 people over all its trips that day.
The answer: 640

Question: A passenger train transports passengers between two stations located in two separate cities. On a particular day, the train carried 100 passengers from one station to the other one way, and on the return trip carried 60 passengers. If the train made three more round trips that day, taking the same number of people as the first trip in each trip, calculate the total number of passengers transported between both stations?


He pays for 20 / 2 = 10 pounds of steaks. That cost 10 * 15 = $150.
The answer: 150
Reverse engineering the question: James buys steaks for buy one get one free. The price is $15 per pound and he buys 20 pounds. How much did he pay for the steaks?


Reasoning and answer: If Rhett is currently paid $5000 per month, he pays 10 / 100 * $5000 = $500 in taxes. Rhett has been late on two of his monthly rent payments and plans to pay them with 3 / 5 * $4500 = $2700 from his salary after taxes. If he is to pay $2700 for two late monthly rent payments, his monthly rent expense is $2700 / 2 = $1350.
The answer: 1350

Question: Rhett has been late on two of his monthly rent payments, but his landlord does not charge late fees and so he will be able to pay their total cost with 3/5 of his next month's salary after taxes. If he is currently paid $5000 per month and has to pay 10% tax, calculate his rent expense per month?


First, we find out how much in sales the stand makes each hour by multiplying the number of hot dogs sold by the sales price, finding that 2 * 10 = 20 dollars in sales each hour. Then we divide the sales goal for the day by the sales per hour, finding that the stand needs to be open for 200 / 20 = 10 hours to hit its sales goal.
The answer: 10
Reverse engineering the question: A hot dog stand sells 10 hot dogs every hour, each one selling for $2. How many hours does the stand need to run to make $200 in sales?


Reasoning and answer: If he finished the race, it would've taken 5 minutes because 2.5 x 2 = 5. Their total time would've been 8 minutes because 3 + 5 = 8. The average would've been 4 minutes because 8 / 2 = 4. The average time in seconds would've been 240 because 4 x 60 = 240.
The answer: 240

Question: Carlos and Diego are racing around the block. Carlos runs around the entire block in 3 minutes. Diego runs around half the block in 2.5 minutes and then is tripped by a dog and can't finish. Assuming he kept up the same speed the entire race, what would've been the average time in seconds for the racers?


Reasoning and answer: Kate bought 7 packs × 18 balls / pack = 126 red bouncy balls. She also bought 6 packs × 18 balls / pack = 108 yellow bouncy balls. Kate bought 126 balls - 108 balls = 18 more red bouncy balls than yellow bouncy balls.
The answer: 18

Question:
Kate bought 7 packs of red bouncy balls and 6 packs of yellow bouncy balls. Each pack contained 18 bouncy balls. How many more red bouncy balls than yellow bouncy balls did Kate buy?
