Reasoning and answer: The time the singer had for singing was 80 - 10 = 70 minutes. The time the singer had for singing 5 - minute songs was 70 - 10 = 60 minutes. The number of 5 - minute songs was 60 / 5 = 12 songs. The total number of songs sung is 12 + 1 = 13 songs.
The answer: 13

Question: Jay went to watch a singer in a one hour 20 minutes concert. If there was a 10-minute intermission, and all the songs were 5 minutes except for one song that lasted 10 minutes, how many songs did she sing?


Paula bought 45 cookies - 3 cookies = 42 cookies. In total, they have 42 cookies + 45 cookies = 87 cookies.
The answer: 87
Reverse engineering the question: Paul and his sister Paula went to the cookie store to buy some cookies. Paula bought 3 fewer cookies than Paul, who bought 45 cookies. How many cookies do they have altogether?


Reasoning and answer: If 5,000 square feet represents one - quarter of the second floor storage space, then the second floor has 5,000 * 4 = 20,000 square feet of storage space. Since the first floor has twice as much space as the second floor, then the first floor has 20,000 * 2 = 40,000 square feet of storage space. Altogether, when empty, the entire building has 20,000 + 40,000 = 60,000 square feet of storage space. Since the second floor has 5,000 square feet of storage space filled with boxes, then there are 60,000 - 5,000 = 55,000 square feet of unused storage space still available in the building.
The answer: 55000

Question: Bubba bought a new two-story warehouse. When empty, the first floor of the building contains twice as much floor space for storage as the second floor. The first items he brought into his empty building were several thousand boxes; and he put them all on the second floor, which filled one-quarter of the second floor storage space. If the boxes used up 5,000 square feet of storage space, how many square feet of storage space is still available in the building?


They sell twice as much raspberry jelly as plum jelly, so they sold 2 * 6 = 12 jars of raspberry jelly today. The raspberry jelly sells a third as much as the grape jelly, so they sold 12 * 3 = 36 jars of grape jelly today. The grape jelly sells twice as much as the strawberry jelly, so they sold 36 / 2 = 18 jars of strawberry jelly today.
The answer: 18
Reverse engineering the question: A grocery store has 4 kinds of jelly. They sell grape jelly twice as much as strawberry jelly, and raspberry jelly twice as much as plum jelly. The raspberry jelly sells a third as much as the grape jelly. If they sold 6 jars of plum jelly today, how many jars of strawberry jelly did they sell?


Reasoning and answer: Roger originally had 4 cans of silly string + 2 can he gave to his brothers = 6 cans. Since his friends received the same amount as Roger did originally, 3 friends x 6 cans of silly string = 18 cans. Michelle started with 6 cans that went to Roger + 18 cans that went to his friends = 24 cans of silly string.
The answer: 24

Question: Michelle had some leftover cans of silly string from her birthday party. She split them among Roger and 3 of his friends. Then Roger decided to give 2 of his cans to his brothers so that he now has 4 for himself. How many cans of silly string did Michelle have to start with?


Reasoning and answer: If there are 3 identical cylindrical structures, with a combined total of 72 rooms, then each individual cylindrical structure contains 72 / 3 = 24 rooms. In each 24 - room cylindrical structure, there are 24 - 12 - 7 = 5 kitchens. Thus, the entire, three - cylinder space station contains a total of 3 * 5 = 15 kitchens.
The answer: 15

The space station, Lupus-1, is an enormous spacecraft made up of three identical cylindrical structures that house the living quarters for the crew.  The three cylindrical structures are linked together by a series of tunnels that hold them together and allow the crew to move between cylinders. Each cylindrical structure contains 12 bedrooms, 7 bathrooms, and several kitchens. If the entire space station has 72 rooms, how many kitchens are there on the entire space station?
