There are 3 x 10 = 30 photos in total that can be placed in the first 10 pages. There are 4 x 10 = 40 photos in total that can be placed in the next 10 pages. A total of 10 + 10 = 20 pages of the album have been used. A total of 30 + 40 = 70 photos can be placed on those 20 pages. So there are still 100 - 70 = 30 photos left to be placed on the album. And there are 30 - 20 = 10 pages left in the album. Therefore, 30 / 10 = 3 photos can be placed on each of the pages.
The answer: 3
Reverse engineering the question: Alyssa took 100 photos on vacation. She wants to put them in a photo album with 30 pages. She can place 3 photos each on the first 10 pages. Then she can place 4 photos each on the next 10 pages. If she wants to put an equal number of photos on each of the remaining pages of the album, how many photos can she place on each page?


Reasoning and answer: If Tenisha has 40 dogs, the number of female dogs is 60 / 100 * 40 = 24. 3 / 4 of the females give birth, meaning 3 / 4 * 24 = 18 female dogs gives birth to puppies. Since each dog that gave birth had 10 puppies, the number of puppies that were born is 18 * 10 = 180. After donating 130 puppies to the church, Tenisha remained with 180 - 130 = 50 puppies.
The answer: 50
What was the question?
Question: Tenisha had 40 dogs that she kept at home as pets. If 60% of them are female, and 3/4 of the female gives birth to 10 puppies each, calculate the total number of puppies that Tenisha remains with after donating 130 puppies to the church.


Aliyah packs her lunch ½ the time, so in 180 school days / 2 = she packs her lunch 90 times. Becky packs her lunch ½ as much as Aliyah, so 90 times / 2 = 45 times a year.
The answer: 45
Reverse engineering the question: There are 180 school days in the academic year. Aliyah packs a lunch half the time. Becky packs her lunch half as much as Aliyah. How many days a year does Becky pack her lunch?


Reasoning and answer: Half the cans collected by Martha is 90 / 2 = 45. So, Diego collected 45 + 10 = 55 cans. Martha and Diego collected 90 + 55 = 145 cans together. Thus, they need to collect 150 - 145 = 5 more cans.
The answer: 5
What was the question?
Question: Martha collected 90 cans while Diego collected 10 more than half the cans collected by Martha. If both of them should collect a total of 150 cans for their project, how many more cans do they need to collect?


The height is 20 feet taller than 500 feet, or 500 + 20 = 520 feet. The structure is 234 feet wider than it is tall, or a width of 520 + 234 = 754 feet wide. Therefore, the sum of the height and width of the Great Pyramid of Giza is 520 + 754 = 1274 feet.
The answer: 1274
Reverse engineering the question: The Great Pyramid of Giza was the tallest man-made structure on earth for almost 4000 years. It is 20 feet taller than 500 feet, and 234 feet wider than it is tall. What is the sum of the height and width of the Great Pyramid of Giza in feet?


If Lydia has 60 bananas, and Dawn has 40 more, then Dawn has 60 + 40 = 100 bananas. The total number of bananas Dawn and Lydia have is 100 + 60 = 160 bananas. Donna has 200 - 160 = 40 bananas.
The answer: 40
