Question: Joe found a new series to watch with a final season that will premiere in 10 days. The series has 4 full seasons already aired; each season has 15 episodes. To catch up with the season premiere he has to watch all episodes. How many episodes per day does Joe have to watch?


Dexter have 9 x 15 = 135 basketball cards. He filled 9 - 3 = 6 plastic boxes with football cards. So, he has 6 x 20 = 120 football cards. Therefore, Dexter has 135 + 120 = 255 cards in total.
The answer: 255
Reverse engineering the question: Dexter filled 3 fewer plastic boxes with football cards than basketball cards. He filled 9 boxes with basketball cards and each box has 15 cards. For the boxes with football cards, he filled each box with 20 cards. How many cards does Dexter have in total?


Reasoning and answer: There are 50 + 16 = 66 passengers at first. Then 66 - 22 = 44 passengers remain. Since 5 more passengers get on the bus there are 44 + 5 = 49 passengers on the bus.
The answer: 49

Question: There are 50 passengers on a bus. At the first stop, 16 more passengers get on the bus. On the other stops, 22 passengers get off the bus and 5 passengers more get on the bus. How many passengers are there on the bus in total at the last station?


With the sick children who stayed home, there are this many kindergarten students in the class: 24 - 2 = 22 kids. This many jellybeans are eaten: 22 x 3 = 66 jellybeans. This many jellybeans are still left in the jar: 100 - 66 = 34 jellybeans.
The answer: 34
Reverse engineering the question: There are 100 jellybeans in a glass jar. Mrs. Copper’s kindergarten class normally has 24 kids, but 2 children called in sick and stayed home that day. The remaining children who attended school eat 3 jellybeans each. How many jellybeans are still left in the jar?


Reasoning and answer: First, we set up the equation 3x = 120, dividing both sides by three to find that x = 40. Then we multiply X by 2 to find that 40 * 2 = 80. As 80 / 2 = 40, and 40 + 80 = 120, we find the sizes of the two piles as the larger pile is twice as big as the smaller pile, confirming that 80 is the answer.
The answer: 80

Question: If two piles of toys added together make 120 toys in total, and the larger of the two piles is twice as big as the smaller one, how many toys are in the larger pile?


Reasoning and answer: Susan needs to make 30 / 2 = 15 batches of the recipe. Therefore, she will need 15 * 4 = 60 potatoes. She will also need 1 * 15 = 15 teaspoons of salt. Thus she will have to buy 15 / 5 = 3 containers of salt. Therefore, she will spend 60 * $.1 = $6 on potatoes and 3 * $2 = $6 on salt. Thus, she will spend $6 + $6 = $12 on food.
The answer: 12
What was the question?
