Reasoning and answer: The drive has 1.5 * 2000 = 3000 kilobytes of storage space. It already has 1.5 * 400 = 600 kilobytes of storage space taken up. Thus, it has 3000 - 600 = 2400 kilobytes of space left. The portable drive can store 2400 / 200 = 12 200 - kilobyte videos on it with 400 photos.
The answer: 12

Reasoning and answer: After taking in 100 more dogs, the number of dogs in the rescue center increased to 200 + 100 = 300. After a week, the number of dogs was reduced to 300 - 40 = 260 after the adoptions. So, there are 260 - 60 = 200 dogs left after 60 more dogs were adopted.
The answer: 200
