There are 48 adults because 120 x .4 = 48. 60% of members are children because 100 - 40 = 60. There are 72 children because 120 x .6 = 72. There are 24 more children than adults because 72 - 48 = 24.
The answer: 24
Reverse engineering the question: A church has 120 members. 40% are adults. The rest are children. How many children more children are there than adults?
Reasoning and answer: Between grapes and mangoes, we have 13 + 20 = 33 crates. The remaining crates are passion fruits, so we have 50 - 33 = 17 crates of passion fruit.
The answer: 17

Tina has already cleaned one key so she has 14 left which take 3 minutes each to clean, 14 x 3 = 42 minutes to clean all the keyboard keys. Her assignment will take 10 minutes to complete, so she needs 42 minutes + 10 minutes = 52 minutes total before dinner.
The answer: 52
Reverse engineering the question: Tina is working on her homework when she realizes she's having a hard time typing out her answers on her laptop because a lot of the keys are sticky. She is trying to get her homework done before dinner, though, so she needs to decide if she has time to clean her keyboard first. Tina knows her assignment will only take 10 minutes to complete. Dinner will be ready at 5:30 p.m. Tina decides to time how long it takes to remove and clean one key and will then multiply that time by how many keys she needs to fix. She counts 15 keys that are sticky and times it to take 3 minutes to clean one. After Tina has cleaned one key, there are 14 left to clean. How many minutes total will it take for Tina to both clean the remaining keys and finish her assignment?
Reasoning and answer: To make a profit of $80, she needs to make $80 + $20 = $100. She needs to sell $100 / $2 = 50 cups of lemonade.

What was the question?
Question: Alexa has a lemonade stand where she sells lemonade for $2 for one cup. If she spent $20 on ingredients, how many cups of lemonade does she need to sell to make a profit of $80?
Each of Gina's account has $3456 / 4 accounts = $864 / account. Her combined account balance is therefore $864 + $864 = $1728.
The answer: 1728
Reverse engineering the question: Gina has two bank accounts. Each account has a quarter of the balance in Betty's account. If Betty's account balance is $3,456, what is the combined balance of both Gina's accounts?
1 / 6 * 240 students = 40 students. So 40 students read three or more novels. 35 / 100 * 240 students = 84 students. So 84 students read two novels. 5 / 12 * 240 students = 100 students. So 100 students read a novel. 240 students (40 students + 84 students + 100 students) = 240 students 224 students = 16 students. So 16 students don't read novels.
The answer: 16
Reverse engineering the question:
240 sixth-grade students were asked about the number of novels they read per month. 1/6 of students read three or more novels, 35% of students read two novels, 5/12 of students read one novel, and the rest of the students do not read anything. Calculate the number of students who do not read novels.
