Question: If it takes 10 people 10 days to shovel 10,000 pounds of coal, how many days will it take half of these ten people to shovel 40,000 pounds of coal?
Answer: The 10 people shovel 10,000 pounds per 10 days, or 10,000 / 10 = 1000 pounds per day per 10 people. And 1000 pounds per day per 10 people is 1000 / 10 = 100 pounds per day per person. Half of ten people is 10 / 2 = 5 people. At 100 pounds per day per person, 5 people can shovel 5 * 100 = 500 pounds per day. Therefore, for 5 people to shovel 40,000 pounds, it will take 40,000 / 500 = 80 days. The answer is 80.
[Question]There are 235 books in a library. On Tuesday, 227 books are taken out. On Thursday, 56 books are brought back and 35 books are taken out again on Friday. How many books are there now?
[Answer]On Tuesday, 227 books were taken, so there are 235 - 227 = 8 books left. 56 books were brought back on Thursday, so there are 8 + 56 = 64 books in the library. Finally, 35 books are taken out on Friday, leaving 64 - 35 = 29 books available. The answer is 29.
Q: In a spelling contest held in her school, Drew got 20 questions correct, winning her the competition. She got six questions wrong, and her competitor Carla got 14 questions correct, and twice as many questions wrong as the number of questions Drew got wrong. If each competitor was asked a different question, how many questions were asked in the competition?
A: Since Drew got 20 questions right and 6 wrong, she was asked 20 + 6 = 26 questions. Carla got twice as many questions wrong as Drew got, a total of 2 * 6 = 12 questions wrong. The total number of questions that Carla was asked is 12 + 14 = 26. Altogether, there were 26 + 26 = 52 questions that were asked in the contest. The answer is 52.
Question: Jackson is making dinner. He makes a salad out of lettuce (50 calories), carrots (twice the calories of the lettuce) and dressing (210 calories). He also makes a pizza with 600 calories for the crust, 1/3 the crust's calories for the pepperoni, and 400 calories for the cheese. If Jackson eats 1/4 of the salad and 1/5 of the pizza, how many calories does he eat?
Answer: First find the number of calories in the carrots: 50 calories * 2 = 100 calories. Then find the total calories in the salad: 100 calories + 50 calories + 210 calories = 360 calories. Then find the number of calories in the pepperoni: 1 / 3 * 600 calories = 200 calories. Now find the total number of calories in the pizza: 200 calories + 600 calories + 400 calories = 1200 calories. Now find how many calories are in Jackson's portion of the salad: 360 calories * 1 / 4 = 90 calories. Now find how many calories are in Jackson's portion of the pizza: 1200 calories * 1 / 5 = 240 calories. Now find the total calories Jackson ate: 90 calories + 240 calories = 330 calories. The answer is 330.

[Question]Page collects fancy shoes and has 80 pairs in her closet. She decides to donate 30% of her collection that she no longer wears. After dropping off her donation, she treats herself and buys 6 more pairs to add to her collection. How many shoes does she have now?
[Answer]
She donates 30% of her 80 pairs of shoes so that’s .30 * 80 = 24 pair of shoes she donates. She had 80 shoes in her collection and donates 24 so that leaves 80 - 24 = 56 pairs of shoes. She now has 56 pairs of shoes and buys 6 more pairs so her collection is now 56 + 6 = 62 pairs of shoes. The answer is 62.
