Max can deliver a maximum of 35 * 7 = 245 packages in one week. For two days Max has carried the maximum number of packages, which in total means 2 * 35 = 70 packages. One day Max has carried only 1 / 7 of the maximum capacity, that is 1 / 7 * 35 = 5 packages. On two other days, Max delivered only 4 / 5 * 35 = 28 packages. That means, Max could deliver 245 - 28 - 5 - 70 - 50 = 92 more packages.
The answer: 92
Reverse engineering the question: Max works for a delivery company as a courier. During one working day, he can deliver a maximum of 35 packages. One week, Max delivered the maximum number of packages, only twice. On two other days, Max unloaded a total of 50 packages, and on one day he unloaded only one-seventh of the maximum possible daily performance. On the last two days, the sum of the packages transported was only fourth-fifth of the maximum daily performance. How many more packages could Max deliver during that week, if he would work at maximum performance?


Reasoning and answer: There were 72 / 2 = 36 laptops sold. There were 72 / 3 = 24 netbooks sold. So, there were a total of 36 + 24 = 60 laptops and netbooks sold. Thus, 72 - 60 = 12 desktop computers were sold last month.
The answer: 12
What was the question?
Question: Mr. Lu owns a computer store. For last month, half of their sales are laptops, one-third are netbooks, and the rest are desktop computers. If Mr. Lu's store was able to sell a total of 72 computers, how many of them are desktop computers?


There are 500 / 5 = 100 four leaf clovers. There are 100 / 4 = 25 purple four leaf clovers.
The answer: 25
Reverse engineering the question: In a field of 500 clovers, 20% have four leaves and one quarter of these are purple clovers. Assuming these proportions are exactly correct, how many clovers in the field are both purple and four-leaved?


Reasoning and answer: The children watch a total of 45 x 4 = 180 minutes in a week. In hours, this is equal to 180 / 60 = 3 hours a week. Thus, these children watch 3 x 2 = 6 hours in two weeks.
The answer: 6
What was the question?
Question: Based on a 2008 study, children 6–11 years old spend 45 minutes each day watching television. How many hours do these children watch television in 2 weeks if they are allowed to watch television 4 days a week?
