Today is the first day of 2008. My brother and I had a good time ~ playing video games. When we were excited, my mother suddenly came over and said, "Stop playing!" " You are nearsighted, and you still play! ""if you are nearsighted, let him be nearsighted.
Get down! ~ ""Mom gives you a problem, and if you solve it, you are allowed to continue playing. If you can't do it, hey, do my homework at once! "I'm afraid. It won't be a simple topic. I'm already dead. So mom drives.
The question is:
Xiao Zhao, Xiaoqian and Sun Xiao are three people. One is a lawyer, the other is a doctor and the other is a teacher. Now I only know:
Sun Xiao is older than the teacher.
(2) Xiao Zhao and doctors are different in age.
(3) The doctor is younger than Penny.
Can you determine who is a lawyer, a doctor or a teacher?
I read this question and thought: it's not easy. So I started to solve the problem. According to (2) Xiao Zhao and the doctor are different in age, and (3) the doctor is younger than Xiao Gan, it can be determined that Xiao Zhao and Xiao Gan are not doctors, so Sun Xiao is a doctor. Re-based
(1) Sun Xiao is older than the teacher, while (3) the doctor is younger than Xiaoqian. It can be known that Sun Xiao (doctor) is older than the teacher and younger than Xiaoqian. It can be seen that Penny and the teacher are not the same person. Penny is a lawyer, and so is Xiao Zhao.
Teacher! After answering the question, my mother had to let me play video games.
