The average test score was 90 and Marco scored 10% less so 90 * .10 = 9 points lower. The average test score was 90 and Marco scored 9 points less so his test score was 90 - 9 = 81. Margret received 5 more points than Marco whose test score was 81 so she made 5 + 81 = 86 on her test.
The answer: 86
Reverse engineering the question: The average score on last week's Spanish test was 90. Marco scored 10% less than the average test score and Margaret received 5 more points than Marco. What score did Margaret receive on her test?


Reasoning and answer: Mr. Johnson has been taking the pills for 30 * 4 / 5 = 24 days. He has 30 - 24 = 6 days left to finish the pills. Thus, Mr. Johnson is supposed to take 12 / 6 = 2 pills a day.
The answer: 2
What was the question?
Question: Mr. Johnson has a prescription with enough pills for 30 days. After four-fifths of the days, he has 12 pills left. How many pills is Mr. Johnson supposed to take a day if he takes the same dose daily?


There will be $100 / $50 = 2 pieces of $50 when $100 is changed to $50 bills. Half of $100 is $100 / 2 = $50. So there will be $50 / $10 = 5 pieces of $10 when $50 is changed to $10 bills. The remaining $50 will be changed to $5 bills so there will be $50 / $5 = 10 pieces of $5 bills. So in total, Lorie will have 2 $50 bills + 5 $10 bills + 10 $5 bills = 17 pieces of bills.
The answer: 17
Reverse engineering the question: Lorie has 2 pieces of $100 bills. He requested to change one piece of the $100 bills into $50 bills. Half of the remaining $100 bill is changed to $10 bills while the rest is changed to $5 bills. How many pieces of bills will she have?


Reasoning and answer: Karen and Donald and their 6 children are a party of 1 + 1 + 6 = 8 people. Tom and Evan and their 4 children are a party of 1 + 1 + 4 = 6 people. All total, there are 8 + 6 = 14 people at the beach house. There are 16 legs in the pool and everyone has 2 legs so there are 16 / 2 = 8 people in the pool. There are 14 people total at the beach house and 8 people are in the pool so 14 - 8 = 6 people are not in the pool.
The answer: 6
What was the question?
Question: Karen and Donald and their 6 children are sharing a beach house with Tom and Eva and their 4 children. If there are 16 legs in the pool, how many people are not in the pool?


If you answer every question correctly in the test, the total possible marks are 50 * 2 = 100 marks. If Jose got five questions wrong, he lost 5 * 2 = 10 marks because each question has two marks. Therefore, Jose scored 100 - 10 = 90 marks on the test. Meghan scored 20 marks less than that which Jose got, a total of 90 - 20 = 70 marks. The total marks that Jose and Meghan scored in the test are 70 + 90 = 160. Alisson scored 90 - 40 = 50 marks in the examination, 40 marks less than that which Jose scored on the test. The total number of marks that the three scored in the test is 160 + 50 = 210.
The answer: 210
Reverse engineering the question: In a 50-question test with two marks for each question, Meghan learned that she scored 20 marks less than her friend Jose, who scored 40 more marks than their friend Alisson. Calculate the total score for the three in the test combined if Jose got 5 questions wrong?


His favorite player scored 150 total points that week because 30 plus 28 plus 32 plus 34 plus 26 equals 150. He averaged 30 points a game because 150 divided by 5 equals 30. He gets paid $10,000 because that's how much he gets if he averages 30 or more points that week.
The answer: 10000
Reverse engineering the question:
James's favorite basketball player got paid based on how many points he averaged each week. He gets $10,000 if he averages 30 or more points a game and $8,000 if he averages under 30 points a game. For his last week, in the first game he scored 30 points and in the second game he scored 28 points. In the third game he scored 32 points. In the fourth game he scored 34 points and in the fifth game he scored 26 points. How much does he get paid for the week?
