If the first bowl has a capacity of 3 / 4 of the second bowl, it's holding 3 / 4 * 600 = 450 marbles. Together, the two bowls are holding 450 + 600 = 1050 marbles.
The answer: 1050
Reverse engineering the question: Two bowls are holding marbles, and the first bowl has a capacity equal to 3/4 the capacity of the second bowl. If the second bowl has 600 marbles, calculate the total number of marbles both bowls are holding together.


Reasoning and answer: Alvin needs to harvest 90 / 3 = 30 coconuts to earn $90. Therefore, the total number of trees that he has to harvest is 30 / 5 = 6.
The answer: 6
What was the question?
Question: Alvin owns coconut trees that yield 5 coconuts each. If a coconut can be sold for $3 and Alvin needs $90, how many coconut trees does he have to harvest?


First find the total time Janet spends looking for her key and complaining each day: 8 minutes / day + 3 minutes / day = 11 minutes / day. Then multiply that number by the number of days in a week to find the weekly time spent: 11 minutes / day * 7 days / week = 77 minutes.
The answer: 77
Reverse engineering the question: Every day Janet spends 8 minutes looking for her keys and another 3 minutes complaining after she finds them. If Janet stops losing her keys, how many minutes will she save every week?


Reasoning and answer: Statistics: 120 / 2 = 60. Seniors in Stats:60(.90) = 54.
The answer: 54
What was the question?
Question: Mr. Angstadt has 120 students throughout the school day. Half of them are enrolled in Statistics. Of the students in Statistics, 90 percent are seniors. How many of Mr. Angstadt's students are seniors enrolled in Statistics?


The price of the tea was twice the price of the cheese, so the cheese cost was 10 / 2 = $5. The price of the butter was 80 / 100 * 5 = $4. If the bread was 2 times cheaper than butter, that means it cost 4 / 2 = $2. That means Ursula paid for all her shopping 2 + 4 + 5 + 10 = $21.
The answer: 21
Reverse engineering the question: Ursula went to the store and bought butter, bread, a package of cheese, and tea. The bread was 2 times cheaper than the butter, while the price of the butter was 80% of the price of cheese. Tea was the most expensive and cost twice the price of a package of cheese. If the tea cost $10, how much did Ursula pay for her purchases?


We know that Josh must be 30 years older than his age when they got married, therefore he is 30 + 22 = 52 years old today. If their current combined age is 5 times the age Josh was when they married (22), then their total combined age is 5 * 22 = 110 years. That means that Anna must be 110 - 52 = 58 years old today. If they married 30 years ago, Anna must have been 58 - 30 = 28 years old when they married.
The answer: 28
Reverse engineering the question:
Josh and Anna were both born on August 17th, but in different years. To consolidate celebrations they also got married on August 17 when Josh turned 22. If today they're celebrating 30 years of marriage and their combined age is exactly 5 times what Josh's age was when they married, how old was Anna when they got married?
