If Monica took ten subjects, Marius took 10 + 4 = 14 subjects. Marius and Monica have 14 + 10 = 24 subjects which they've taken. Since Millie is taking three more subjects than Marius, she is taking 14 + 3 = 17 subjects. Together, the three have taken 24 + 17 = 41 subjects.
The answer: 41
Reverse engineering the question: Millie, Monica, and Marius are taking subjects for school. Millie takes three more subjects than Marius, who takes 4 subjects more than Monica. If Monica took 10 subjects, how many subjects all take altogether?


Reasoning and answer: Hansel makes $30,000 and received a 10% raise so his raise is 30,000 * .10 = $3,000.00. Hansel now makes 30,000 + 3,000 = $33,000 a year. Gretel makes $30,000 and received a 15% raise so her raise is 30,000 * .15 = $4,500.00. Gretel now makes 30,000 + 4,500 = $34,500 a year. If Gretel makes $34,500 a year and Hansel makes $33,000 then Gretel makes 34,500 - 33,000 = $1,500 more a year than Hansel.
The answer: 1500
What was the question?
Question: Hansel makes $30,000 a year and just received a 10% raise. Gretel makes the same amount as Hansel but received a 15% raise. How much more money will Gretel make compared to Hansel?


Matthew scored 9 points and there are 3 points per basket, so he made 9 / 3 = 3 baskets. Shawn scored 6 points, so he made 6 / 3 = 2 baskets. The total number of baskets made is 3 + 2 = 5 baskets made.
The answer: 5
Reverse engineering the question: Matthew and his brother Shawn played swimming-pool-basketball. Each basket was worth 3 points. Matthew scored 9 points. Shawn scored 6 points. What is the total number of baskets made during this game?


Reasoning and answer: The population of Gordonia is 1 / 2 * 80000 people = 40000 people. Toadon has 60 / 100 * 40000 people = 24000 people. The total population of Gordonia and Toadon is 40000 people + 24000 people = 64000 people. The population of Lake Bright is 80000 people - 64000 people = 16000 people.
The answer: 16000
What was the question?
Question: Three towns, Toadon, Gordonia, and Lake Bright, have 80000 people. Gordonia has 1/2 times the total population in the three cities. If the population of Toadon is 60 percent of Gordonia's population, how many people live in Lake Bright?


Since there are 100 units, the number of units occupied by tenants is 3 / 4 * 100 = 75. If each tenant pays $400 every month, Mr Maximilian receives 75 * $400 = $30000 in rent revenue every month. In a year, Mr Maximilian receives $30000 * 12 = $360000 in rent revenue.
The answer: 360000
Reverse engineering the question: Mr. Maximilian has a rental building that he collects rent from every month. The number of units in the building is 100. If the building is 3/4 occupied for a whole year, and each resident of the building pays a rent of $400, calculate the amount of money Mr. Maximilian receives in that year.


Shara collected 5 x 3 = 15 shells for 3 days. So she collected 15 + 6 = 21 shells rom her vacation. Thus, she now has a total of 20 + 21 = 41 shells.
The answer: 41
Reverse engineering the question:
Shara collects shells. She had 20 shells before she went on vacation. On vacation, she found 5 shells per day for 3 days. Then he found 6 shells on the fourth day. How many shells does she have now?
