Steve spends 24 / 3 = 8 hours sleeping. He spends 24 / 6 = 4 hours in school. He spends 24 / 12 = 2 hours making assignments. He spends 8 + 4 + 2 = 14 hours either sleeping, going to school, or making assignments. Hence, Steve spends 24 - 14 = 10 hours with his family.
The answer: 10
Reverse engineering the question: Steve spends 1/3 of the day sleeping, 1/6 of the day in school, 1/12 of the day making assignments, and the rest of the day with his family. How many hours does Steve spend with his family in a day?


Reasoning and answer: The 4 chairs cost Cory $135 - $55 = $80. Each chair costs $80 / 4 = $20.
The answer: 20
What was the question?
Question: Cory bought a patio table and 4 chairs for $135. The patio table cost $55. If each chair cost the same amount, how much did each chair cost?


Sonja will spend $3 + $23 = $26. Barbara will spend 5 + ( 2 * 2) = $9. Mario and Rick will spend 2 * 3 = $6. Everyone but Sonijs spend $9 + $6 + $4 = $19. Sonija spent $26 - $19 = $7 more than the rest of the people at the party.
The answer: 7
Reverse engineering the question: Five people are planning a party. Sonja will buy a loaf of French bread ($3 a loaf) and a platter of cold cuts ($23). Barbara will buy the soda ($1 per person) and two boxes of crackers ($2 per box). Mario and Rick will split the cost of two packages of Cheese Doodles ($3 per package). Danica will supply a package of paper plates for $4. How much more will Sonja spend than the rest of the office put together?


Reasoning and answer: If Judson paid $500, Kenny contributed 20 / 100 * $500 = $100 more than Judson. In total, Kenny contributed $500 + $100 = $600. Kenny and Judson contributed a total of $600 + $500 = $1100. If Camilo contributed $200 more than Kenny, then he contributed $600 + $200 = $800. The total amount of money the three contributed for the house painting is $1100 + $800 = $1900.
The answer: 1900
What was the question?
Question: Judson, Camilo, and Kenny decided to contribute money to paint their house. Judson contributed $500, Kenny contributed 20% more money than Judson, and Camilo contributed $200 more than Kenny. How much was the cost of painting the house?


In 11 months, Yoque will pay a total of $15 x 11 = $165. The amount $165 is 100% + 10% = 110% of the money she borrowed. So, 1% is equal to $165 / 110 = $1.50. Hence, Yoque borrowed $1.50 x 100 = $150.
The answer: 150
Reverse engineering the question: Yoque borrowed money from her sister. She promised to pay it back in 11 months including an additional 10% of the money she borrowed. If she pays $15 per month, how much money did she borrow?


In five years, Angelina will be 40 years old, meaning currently she is 40 - 5 = 35 years old. Since Angelina is 35 years old right now, and she is four years older than Justin, it means Justin is 35 - 4 = 31 years old.
The answer: 31
Reverse engineering the question:
Angelina is 4 years older than Justin is now. In 5 years, Angelina will be 40 years old. Calculate the age of Justin currently.
