Reasoning and answer: After the first spray kills 50% of germs, there will be 100 - 50 = 50% left. The second spray kills 25%, but 5% have already been killed by the 50% spray, so it kills 25 - 5 = 20%. After the second spray kills 20% of the remaining germs, there will be 50 - 20 = 30% left.
The answer: 30
What was the question?
Question: A cleaning company produces two sanitizer sprays. One spray kills 50% of germs, and another spray kills 25% of germs. However, 5% of the germs they kill are the same ones. What percentage of germs would be left after using both sanitizer sprays together?


First find the total number of goldfish Millie adds: 64 pretzels * 4 goldfish / pretzel = 256 goldfish. Then add the number of each kind of snack to find the total: 256 goldfish + 64 pretzels + 32 suckers = 352 snacks. Then divide the total number of snacks by the number of baggies to find the number of snacks per baggie: 352 snacks / 16 baggies = 22 snacks / baggie.
The answer: 22
Reverse engineering the question: MIlle is making snack packs for her kindergarten class. She's going to divide 64 pretzels, four times as many goldfish, and 32 suckers into baggies for the 16 kids in the class. How many items does each baggie have?


Reasoning and answer: Eustace’s current age must be 39 years old – 3 years = 36 years old. So Milford’s current age must be 36 years old / 2 = 18 years old. So in 3 years, Milford will be 18 years old + 3 years = 21 years old.
The answer: 21
What was the question?
Question: Eustace is twice as old as Milford. In 3 years, he will be 39. How old will Milford be?


The sales for iPhones were 100 iPhones * $1000 per iPhone on average = $100,000. The sales for iPads today were 20 iPads * $900 per iPad = $18,000. The sales for Apple TV’s today were 80 * $200 = $16,000. The total sales for Apple at their New York store today was $100,000 + $18,000 + $16,000 = $134,000. The total number of products sold was 100 + 20 + 80 = 200. The average cost per product sold was $134,000 total sales / 200 total products = $670.
The answer: 670
Reverse engineering the question: Apple sold 100 iPhones at their New York store today for an average cost of $1000. They also sold 20 iPads for an average cost of $900 and 80 Apple TVs for an average cost of $200. What was the average cost across all products sold today?


Reasoning and answer: Dan spent an hour doing 400 tasks * $.25 = $100. Dan spent an hour doing 5 tasks * $2.00 each = $10.00. Dan made $100 - $10 = $90.00 per hour more doing the higher paid work.
The answer: 90
What was the question?
Question: Dan spent an hour doing 400 work tasks at $0.25 each. Then Dan spent an hour doing 5 work tasks at $2.00 each. How much more did Dan make doing the good work compared to the lower-paid work?


Reasoning and answer: During each boat trip, there can be 12 people onboard, so during 4 boat trips, there can be 4 * 12 = 48 people in total. During two days the boat can transport a total of 48 * 2 = 96 people.
The answer: 96
