Gọi tuổi cháu hiện nay là a 

=> Tuổi cô hiện nay là 6 x a.

=> Tuổi cháu khi bằng tuổi cô hnay: 6 x a

Khi tuổi cháu bằng tuổi cô hiện nay thì tuổi cháu tăng thêm:

          6 x a - a = 5 x a

=> Khi tuổi cháu bằng tuổi cô hiện nay thì tuổi cô lúc đó là:

          6 x a + 5 x a = 11 x a

Ta có:

          6 x a + 11 x a = 68

          => 17 x a       = 68

          =>         a       = 68 : 17

                       a       = 4

     => Tuổi cô hiện nay là: 6 x 4 = 24 (tuổi) 

                          Đ/S:.........

Hi! 
My name is TRINH, I am 20 years old and a student at TAY NGUYEN University. My main subject is business administration. I was born and grew up in DAK LAK. At the moment, I am living with my parents and three brothers. 
I am a quiet, a little bit childish but also factual, dexterous and roman lady. (them) In the education views, I am diligent, clever and patient with my study or even work and I never give up even though I know a lot of hardships are waiting for me in the future. My hobbies are jewellery collections, taking a walk in the afternoon, listening to music and watching movies. Parularly, I really love to watch how to make a sweet cake videos from the internet. I also enjoy playing badminton and riding a bicycle. 
My dream is to be a successful businesswoman so that now I am trying to study as hard as I can to get into the right subject that I love. And I also hope that my dream will come true and surely I will do everything to make it come true. 

​Bài viết mẫu:
My name is Minh Duong Khang and I’m a Vietnamese. I am ten years old. I live in Ho Chi Minh city in the south of Vietnam.

I have a big family with six people. I have two sisters and a brother. My sisters are older and my brother is younger than me. My father is a teacher at a secondary school. He has worked for 35 years in the field and he is my biggest role model in life. My mother is a housewife. She is nice and she is really good at cooking. I love my family so much.

I’m a generous and easy-going person but when it comes to work I’m a competitive perfectionist. I’m also an optimis and outgoing person so I have many friends and other social relationships. I enjoy reading, writing and doing math. I decided to become a Civil Engineer because I have always been fascinated by bridges, buildings, and skyscrapers. A degree in Civil Engineering enables me to achieve my goals and also gives me an opportunity to make a difference in the community.

Five years from now, I want to become a project manager of a construction project. As a project manager, my primary goals are managing people, set budgets, and making decisions of all kinds. I also want to speak English fluently so I can work with people from different countries.
