First subtract the 8 toddlers Bill double - counted from his count: 26 toddlers - 8 toddlers = 18 toddlers. Then add the 3 toddlers he missed to find the real count: 18 toddlers + 3 toddlers = 21 toddlers.
The answer: 21
Reverse engineering the question: Bill is trying to count the toddlers at his daycare, but they keep running around. He double-counts 8 toddlers and misses 3 who are hiding. If Bill thinks he counted 26 toddlers, how many are there really?
Reasoning and answer: He ate 2 * 1 = 2 bags after dinner. So he ate 2 + 1 = 3 bags of chips.
The answer: 3
What was the question?
Question: John eats a bag of chips for dinner and then eats twice as many after dinner. How many bags of chips did he eat?
On weekdays it earns $600 / weekday * 5 weekdays = $3000. During the weekend it earns twice as much each day so it makes ($600 * 2) / weekend day * 2 weekend days = $2400. Every week it earns $3000 + $2400 = $5400. By the end of the month, it earns $5400 / week * 4 weeks = $21600.
The answer: 21600
Reverse engineering the question: An Italian restaurant earns $600 every weekday and twice as much on the weekend. How much money does it earn by the end of the month?
Reasoning and answer: All the animals have 4 legs. His 3 dogs will need 3 * 4 = 12 shoes. His 2 cats will need 2 * 4 = 8 shoes. His ferret will need 1 * 4 = 4 shoes. Olly will need 12 + 8 + 4 = 24 shoes.
The answer: 24
What was the question?
Question: Olly wants to get shoes to protect his pets' paws. He owns 3 dogs, 2 cats, and a ferret. How many shoes does he need?
There are 60 students x 2 / 3 = 40 students who have a $6 daily allowance. While there are 60 students - 40 students = 20 students who have a $4 daily allowance. The sum of the allowances of the 40 students who received $6 daily is 40 students x $6 / day = $240. The sum of the allowances of the 20 students who received $4 daily is 20 students x $4 / day = $80. The total daily amount of money of those 60 students is $240 + $80 = $320.
The answer: 320
Reverse engineering the question: A Statistics student wants to find out the average daily allowance of the middle school students. According to his survey, 2/3 of the students receive an average of $6 allowance per day while the rest gets an average of $4 a day. If he surveyed 60 students, what is the total amount of money those 60 students get in a day?
Jonah spent 6 x $3 = $18. He made a total of 6 x 12 = 72 pineapple rings. He sold 72 / 4 = 18 sets of pineapple rings. He made 18 x $5 = $90. His profit was $90 - $18 = $72.
The answer: 72
Reverse engineering the question:
Jonah bought 6 pineapples for $3 each. Each pineapple could be cut into 12 pineapple rings. He sold 4 pineapple rings for $5 each. How much profit did Jonah make?
