Question: The chances of making the junior high basketball team start at 10% if you're 66 inches and increase 10% for every additional inch of height. Devin starts out as 65 inches tall, then grows 3 inches. What are his chances of making the basketball team?
Answer: Step-by-step reasoning process: First find Devin's new height by adding his growth to the original height: 65 inches + 3 inches = 68 inches. Then subtract 66 inches from Devin's height to find how many extra inches of height he has: 68 inches - 66 inches = 2 inches. Then multiply the number of extra inches by the percentage increase per inch to find the total percentage increase in his chances: 2 inches * 10% / inch = 20%. Then add the percentage increase to the base percentage to find Devin's overall chance of making the basketball team: 10% + 20% = 30%.
So the answer is 30.

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: Step-by-step reasoning process: 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.
So the answer is 29.

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: Step-by-step reasoning process: 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.
So the answer is 90.

Question: The American Academy of Pediatrics recommended no more than 2 hours of screen time each day for children. Mrs. Merril wants to follow a 2-hour screen time for her child. How many minutes will she allow her child to use his gadget this evening if he already used his gadget for 45 minutes in the morning?
Answer:
Step-by-step reasoning process: Mrs. Merril wants to follow 2 hours x 60 minutes / hour = 120 minutes screen time. Since her child already used up 45 minutes, he is allowed to use his gadget this evening for 120 minutes - 45 minutes = 75 minutes.
So the answer is 75.
