Reasoning and answer: There were 80 / 2 = 40 wireless mice sold. There were 80 / 4 = 20 optical mice sold. So, there were a total of 40 + 20 = 60 wireless and optical mice sold. Therefore, 80 - 60 = 20 trackball mice were sold this month.
The answer: 20
What was the question?
Question: Marky owns a computer accessory shop. For this month, half of their sales are wireless mice, one-fourth are optical mice, and the rest are trackball mice. If Marky's shop was able to sell a total of 80 mice, how many of them are trackball mice?
There are 30 / 3 = 10 blue fish. There are 10 / 2 = 5 blue spotted fish.
The answer: 5
Reverse engineering the question: There are 30 fish in the tank. One third of them are blue, and half of the blue fish have spots. How many fish in the tank are blue, spotted fish?
Reasoning and answer: First find the amount of time it takes Marcus to saute the garlic and peppers: 20 minutes / 4 = 5 minutes. Then find the dough's resting time: 30 minutes * 2 = 60 minutes. Then add the kneading and resting time to find the total dough time: 60 minutes + 30 minutes = 90 minutes. Then multiply that amount by 1 / 10th to find the assembly time: 90 minutes / 10 = 9 minutes. Then add the saute time, knead time, rest time and assembly time to find the total time Marcus spends on the calzones: 9 minutes + 20 minutes + 5 minutes + 60 minutes + 30 minutes = 124 minutes.
The answer: 124
What was the question?
Question: Marcus is making calzones. It takes him 20 minutes to saute the onions and a quarter of that time to saute the garlic and peppers. It takes him 30 minutes to knead the dough, twice as long to let it rest, and 1/10th the combined kneading and resting time to assemble the calzones. How many minutes does Marcus spend on the calzones total?
Every day, in addition to her 10 - hour work schedule, Anie needs 5 extra hours, which means she works 10 + 5 = 15 hours each day. If the project is estimated to take 1500 hours, Anie will need to work for 1500 / 15 = 100 days to complete the project.
The answer: 100
Reverse engineering the question: To finish the task assigned to her by the work supervisor in the stipulated deadline, Anie needs 5 hours extra aside from the normal work schedule each day. If each day her work schedule requires her to be productive for 10 hours, and the project is estimated to take 1500 hours, calculate the number of days it would take Anie to finish the job.
Reasoning and answer: Kyle's monthly bills are 1250 + 150 + 400 + 300 + 200 + 200 = $2,500.00. He makes $3200 and his bills are $2500 so that leaves 3200 - 2500 = $700.00. If he buys a car with a monthly car payment of $350 then that leaves 700 - 350 = $350.00 left over for gas and maintenance.
The answer: 350

Question: Kyle makes $3200.00 every month. His monthly bills include $1250 for rent, $150 on utilities, $400 into retirement & savings accounts, $300.00 on groceries/eating out, $200 for insurance and $200 for miscellaneous expenses.

Reasoning and answer: Armand = (1 / 3) * 12 = 4 hours. Ella = 2 * 12 = 24 hours. Total hours = 12 + 4 + 24 = 40 hours. They worked a total of 40 hours.
The answer: 40
