[Question]A class of 12 students was about to share 108 oranges equally among themselves when it was discovered that 36 of the oranges were bad and had to be thrown away. How many oranges less will each student get now than if no orange had to be thrown away?
[Answer]If the 12 students had shared the 108 oranges, each student would have gotten 108 / 12 = 9 oranges. But 36 were removed so there are 108 - 36 = 72 oranges left. So 12 shared 72 for each to get 72 / 12 = 6 oranges. This is 9 - 6 = 3 less than they would each get if they did not have to throw any orange away. The answer is 3.

Question: Ivan has a bird feeder in his yard that holds two cups of birdseed. Every week, he has to refill the emptied feeder. Each cup of birdseed can feed fourteen birds, but Ivan is constantly chasing away a hungry squirrel that steals half a cup of birdseed from the feeder every week. How many birds does Ivan's bird feeder feed weekly?
Answer: The squirrel steals 1 / 2 cup of birdseed every week, so the birds eat 2 - 1 / 2 = 1 1 / 2 cups of birdseed. Each cup feeds 14 birds, so Ivan's bird feeder feeds 14 * 1 1 / 2 = 21 birds weekly. The answer is 21.
[Question]Harry is joining a marathon that's why he practices and varies his workouts from day to day. He ran 10 meters per hour on Monday. From Tuesday to Thursday he ran 50% faster than on Monday. Then on Friday, he ran 60% faster than he ran on Thursday. How fast did Harry run on Friday?
[Answer]Harry ran 10 x 50 / 100 = 5 meters per hour faster on Tuesday to Wednesday. So he ran 10 + 5 = 15 meters per hour from Tuesday to Thursday. Then on Friday, he ran 15 x 60 / 100 = 9 meters per hour more. Therefore, he ran 15 + 9 = 24 meters per hour on Friday. The answer is 24.

Question: There are 40 more buyers in the grocery store today than yesterday. There were half the number of buyers yesterday as there were the day before, and the day before had 50 buyers. Nobody visited the store on more than one day. What's the total number of buyers who've visited the store in the three days?
Answer:
If yesterday the number of buyers was half the number of buyers the day before, then yesterday there were 1 / 2 * 50 = 25 buyers. Today has 40 more buyers than yesterday, so there were 40 + 25 = 65 buyers today. The total number of buyers in the store for the three days will be 65 + 25 + 50 = 140 buyers. The answer is 140.
