Q: Robby doesn't like the color brown and will not eat the brown M&M's. On his first bag, he sets aside 9 brown M&M's. On the second bag, he sets aside 12. On his third & fourth bag, there are 8 brown M&M's that he doesn't eat. On his fifth bag, there are only 3 brown M&M's that he doesn't eat. What's the average number of brown M&M's in a bag?
A: Out of 5 bags, he had 9 + 12 + 8 + 8 + 3 = 40 brown M&M's. He ate 5 bags so the average number of brown M&M's per bag was 40 / 5 = 8 brown M&M's. The answer is 8.
Question: An investor invested some money in 2 separate schemes: A and B. Scheme A will yield 30% of the capital within a year, and scheme B will yield 50% of the capital within a year. If he invested $300 in scheme A and $200 in B, how much more money will he have in scheme A than in B after a year, provided he does not withdraw anything?
Answer: After a year, scheme A will yield 30% of his capital which is (30 / 100) * $300 = $90. In addition to his capital, he will have $90 + $300 = $390 in scheme A. After a year, scheme B will yield 50% of his capital which is (50 / 100) * $200 = $100. In addition to his capital, he will have $100 + $200 = $300 in scheme B. After a year, he will have $390 - $300 = $90 in scheme A more than in scheme B. The answer is 90.

Q: A highway is being extended from its current length of 200 miles up to 650 miles. 50 miles are built on the first day, and three times this amount are built on the second day. How many miles still need to be added to the highway to finish extending it?
A: The length of the highway that needs to be constructed is 650 200 = 450 miles. After the first day, there are still 450 50 = 400 miles that need to be constructed. On the second day, 50 miles * 3 = 150 miles are added to the highway. This means that 400 150 = 250 miles still need to be added to the highway. The answer is 250.
Question: Roosevelt High school plays a basketball tournament with Greendale High school. Roosevelt high school scores 30 points in the first game, half as much in the second game, and triple as much as the second game in the third game. At the end of the tournament, Roosevelt high school receives 50 bonus points and Greendale high school has 10 points less than Roosevelt high school. How many points does Greendale high school have?
Answer: The points Roosevelt high school has for the second game are 30 / 2 = 15 points. The points Roosevelt high school has for the third game are 15 * 3 = 45 points. The total points Roosevelt high school has for the tournament are 30 + 15 + 45 + 50 = 140 points. The total points Greendale high school has for the tournament are 140 - 10 = 130 points. The answer is 130.
Q: Nick's cell phone was initially empty but was then charged for 45 minutes and has reached a 25% charge. How much longer must the cell phone be charged to reach 100% charge?
A:
The ratio between the time charged and the time to be charged is 100 / 25 = 4. To reach 100%, the cell must be charged for 45 minutes * 4 = 180 minutes. Subtracting the 45 minutes that Jimmy already used to charge the cell phone, there are still 180 - 45 = 135 minutes of charging time left. The answer is 135.
