Question: Eighteen hours ago, Beth and I took 100 photographs of our project. Today, Beth and I will take 20% fewer photographs of the same project. If we were to take 300 photographs of the project, how many photographs would we take to reach the target?
Answer: Step-by-step reasoning process: If you took 100 photographs of the project 18 hours ago, and today 20% few photographs have been taken, then 20 / 100 * 100 = 20 fewer photographs of the project have been taken today. The total number of photographs of the project that have been taken today is 100 - 20 = 80. So far, you've taken 80 + 100 = 180 photographs of the project. Since the target number of photographs is 300, the number of photographs that you need to take to reach the target is 300 - 180 = 120.
So the answer is 120.

Question: Oliver is working out in a gym. On Monday he worked out for 4 hours, and the next day for 2 hours less. On Wednesday he decided to work out twice as much as on Monday. On Thursday the gym was closed, so Oliver needed to exercise at home which took twice as much time as on Tuesday. How many hours in total have Oliver worked out during these four days?
Answer: Step-by-step reasoning process: On Tuesday, Oliver worked out for 4 - 2 = 2 hours. On Wednesday he decided to work out twice as much as on Monday, so for 2 * 4 = 8 hours. On Thursday, at home, Oliver trained twice as much as on Tuesday, so for 2 * 2 = 4 hours. In total Oliver trained for 4 + 2 + 8 + 4 = 18 hours.
So the answer is 18.

Step-by-step reasoning process: Since there are four types of chocolate bars and each type has 25 bars, the total number of chocolate bars is 25 * 4 = 100. Since there is a total of 100 chocolate bars and four types of chocolate, we divide 100 / 4 = 25%.
So the answer is 25.
