"这是特种部队招收人员的第三关智力测验题目" really? If you know enough math, you will know the answer. If you are from the other backgrounds, it will be hard for you. Move the poeple to occupy rooms with odd numbers and left even numbered rooms for new comers. Here is an other one for 智力测验. Again, it seems unfair for those without math background. We know a time point does not have a length. For example, 12 AM does not last. So are 12:01, 12:02 and so on. But why when you add all these time points, it will have a length? (For example, between 12 and 1, it is 1 hr) www.ddhw.com
