Reasoning and answer: The total ratio representing the slices of pizza that Buzz bought is 5 + 8 = 13. If he shared the slices of pizza with the waiter, the waiter received a fraction of 8 / 13 of the total number of slices, which totals 8 / 13 * 78 = 48 slices. Twenty less the number of slices of pizza that the waiter ate is 48 - 20 = 28.
The answer: 28

Mary took 10 + 6 = 16 chickens. John took 16 + 5 = 21 chickens. John took 21 - 10 = 11 more chickens than Ray.
The answer: 11
Reverse engineering the question: The Grey's bought several chickens at a sale. John took 5 more of the chickens than Mary took. Ray took 6 chickens less than Mary. If Ray took 10 chickens, how many more chickens did John take than Ray?
Reasoning and answer: The total percentage of students who said they like chess or basketball is 10% + 40% = 50%. So, 250 x 50 / 100 = 125 students like chess or basketball.

The house cost 320,000 * 1.5 = $480,000. So it is worth 480,000 - 320,000 = $160,000 more than other houses. So the profit is 160,000 - 100,000 = $60,000 more.
The answer: 60000
Reverse engineering the question: The cost of building a certain house in an area is 100,000 more than the construction cost of each of the houses in the area. But it sells for 1.5 times as much as the other houses, which sell at $320,000 each. How much more profit is made by spending the extra money to build?
Reasoning and answer: First find the total time spend making the smoothies: 5 smoothies * 3 minutes / smoothie = 15 minutes. Then add that amount of time to the time freezing the ice cubes to find the total time spent: 15 minutes + 40 minutes = 55 minutes.
The answer: 55

Question: It takes 40 minutes to freeze ice cubes and 3 minutes per smoothie to turn them into smoothies once they're frozen. How long does it take to make 5 smoothies?
Reasoning and answer: The second machine made 2.4 times as many necklaces as the first machine, so the second machine made 2.4 * 45 = 108 necklaces on Sunday. In total, 45 + 108 = 153 necklaces were made on Sunday.
The answer: 153
