Step-by-step reasoning process: Let X be the number of students last year. The number of students this year is X + X * 20% = 960. Combining like terms, we get X * 1.2 = 960. Dividing both sides by 1.2, we get X = 800 students.
[Q & A] The question is In my school, the number of students has increased by 20% this year. The number of students this year is 960. How many students were there last year?
The answer is 800

Step-by-step reasoning process: They need 36 slices because 3 x 12 = 36. After ordering the small, they need 28 slices because 36 - 8 = 28. They need 2 large pizzas because 28 / 14 = 2.

Step-by-step reasoning process: Two white socks cost 25 cents more than a single brown sock, meaning a brown sock is sold at $0.45 - $0.25 = $0.20. The cost of buying 15 brown socks is 15 * $0.20 = $3.
[Q & A] The question is Two white socks cost 25 cents more than a single brown sock. If two white socks cost 45 cents, how much would you pay for 15 brown socks?
The answer is 3

Step-by-step reasoning process: If the dog eats two eyes and Oomyapeck eats 22 eyes, then there are a total of 2 + 22 = 24 eyes. With 2 eyes per fish, 24 eyes represent 24 / 2 = 12 fish. If they split that number of fish equally amongst the three of them, then each of them will be given 12 / 3 = 4 fish to eat.
[Q & A]
The question is Ittymangnark and Kingnook are an Eskimo couple living in the most northern region of the Alaskan wilderness. Together, they live with their child, Oomyapeck. Every day Ittymangnark catches enough fish for the three of them to eat for the day and they split the fish equally between the three of them. But after they have split the fish, they give Oomyapeck all of the eyes, who gives two of the eyes to his dog and eats the rest himself. How many fish will each of them be given to eat if Oomyapeck eats 22 eyes in a day?
The answer is 4
