Có chín ngôi nhà liên tiếp trên Phố Deer. Ít nhất hai người sống trong mỗi ngôi nhà. Không có hai ngôi nhà lân cận nơi có hơn mười người sống hoàn toàn. Số người tối đa có thể sống trong chín ngôi nhà là bao nhiêu?

Giải

Ít nhất hai người sống trong một ngôi nhà, không có hai ngôi nhà lân cận nơi có hơn mười người sống hoàn toàn

=> Trong hai ngôi nhà liên tiếp, có thể có một nhà có 8 người và một nhà có 2 người để đạt được số người tối đa có thể sống trong hai nhà liên tiếp (không hơn mười người, tức tối đa 10 người).

=> Có 9 ngôi nhà, tức là trong 4 ngôi nhà có 8 (hoặc 2) người hoặc trong 5 ngôi nhà có 8 (hoặc 2) người .

=> Để đạt được số người tối đa, 5 ngôi nhà mỗi nhà sẽ có 8 người sống và trong 4 ngôi nhà mỗi nhà sẽ có 2 người

=> 8.5 + 2.4 = 40 + 8 = 48

Theo mình nghĩ là vậy nhưng không chắc lắm nhé. Hơn nữa cũng không có đáp án nào là 48 người nên...

Còn nữa mình dịch trên Google tại không giỏi tiếng Anh lắm, có gì sai bạn nhắc mình nhé

1.Vietnam is famous with its traditional and delicious dishes. All of them easioly bring to anyone's mouth indeed, but as myself, I enjoy spring rolls best. Spring rolls are lightly fried rice -paper rolls, smaller and crispier than Chinese egg rolls but more flavorful. They are filled with highly seasons morsels of crab, shrimp, chopped vegetables, onion, mushroom, vermicelli and eggs. To prepare them, place the above mentioned filling on a thin rice pancake, roll up then fry. Finally, spring rolls, when fully prepared, are wrapped into some kinds of fresh vegetables, then doused in fish sauce. My mother usually cooks spring rolls for me, especially on important days in year, such as Tet holiday. When I eat them, I feel all of my mother's love that she reserves for me. To me, they're the most special dish in this world

My favorite sport is badminton. I playing it because I think it is a good sport. Every sport will make people feel hot and uncomfortable, but when you play badminton, you will be comfortable because in the badminton court, there are many air-conditioners.

I usually play badminton on Sunday. I always play with my friend, Linh. She is good at badminton. But I am not very good at this sport so when we play badminton, she hits the ball on my both sides. She makes me run and run, and I feel very tired. Sometimes I must jump high to hit the ball to the opposite side.

Although this makes me tired, I still always practise because I will be healthier and fitter than before. Anyway, I think badminton is the best sport.

I don't want to go out and I have to take a bath many times a day. The cold weather makes me lazier, I sleep more and study less. I go to bed earlier and get up late. I feel uncomfortable when I have to wear a lot of clothes. Moreover, when it is cold, I am usually ill. 
 My favorite weather is cool and has breeze. It is one kind of weather of in spring. Firstly, I can wear many kinds of clothes. I can go out without hat or umbrella.

In future, when robots can be used both in homes and in other areas, it could improve the
standard of living of people. House hold chores took significant cut in humans' life. Many
people burn their energy on their day to day tasks cooking, cleaning etc after coming
from work. When robots can complete such jobs, people can spend more time with their
family and friends. Experts say that many major problems in the modern world are caused
due to miscommunication. When people get more time, they can talk freely and resolve
such issues and eventually create happy society.
Robots can be used on certain jobs to curb accidents due to negligent behaviour of some
people. When robots are used on such work, it does not cause any human life due to
accidents at the work places. Human resource can be efficiently used by involving humans
to perform those tasks which demand human skills crial thinking, problem solving etc
while robots can be used on low end jobs moving cargos, heavy weights lifting etc.
While some people talk about how robots can be useful to human, others voice their
concerns demotion in human values and creation of lazy society due to heavy
dependency on robots. When robots become cheaper to produce, employers may prefer to
use more robots than humans. As the technology constantly improves the capabilities of
robots, it could undermine the values of humans.
Many people may rely on robots heavily. Some may even develop a habit of using robots
on tasks that they can easily do. This could create lazy society. Humans could start to
cherish robots at the expense of human lives.
In conclusion, robots can be used on anything which can eventually improve humans'
standard of living but definitely not at the expense of human lives. Robots can be used to
help humans to live in harmony and to form happy societies. This fundamental setup
should not be allowed to deteriorate by robots.
