Question: 40 kids are running a race. 10% of them pass the finish line in less than 6 minutes. Three times that number finish in less than 8 minutes. 1/6 of the remaining kids take more than 14 minutes. How many kids take more than 14 minutes?
Answer:
First find how many kids finish in under 6 minutes: 40 kids * 10% = 4 kids. Then triple that number to find how many finish in less than 8 minutes: 4 kids * 3 = 12 kids. Then subtract those two numbers from the total number of kids to find the number of remaining kids: 40 kids - 4 kids - 12 kids = 24 kids. Then divide that number by 6 to find how many kids take more than 14 minutes: 24 kids / 6 = 4 kids. The answer is 4.
