Because the master-apprentice cooperation completes 60% of the total in 3 days

Calculate 20% of the work done in 1 day

The master's work efficiency is twice that of the apprentice.

Calculate that the apprentice's ergonomics are 20% (2+1)=1 15 (one-fifteenth) The master's ergonomics is 20%-(1 15)=2 15 set for x days (forgot how to use arithmetic, forgive me)— 20% (x-3) + 3 * (1 15) = 1

20%（x-3）+（1/5)=1

20%（x-3）=4/5

x-3=4x=7

A: Shared 7 days.

Apprentice's work efficiency: 60% 3) (1+2)= 1 15Master's work efficiency: 1 15)*2 = 2 15 Stop work for three days Apprentice complete:

1 15)*3 =1 5 left: 1-60%-1 5 =1 5

The remaining days : 1 5) (1 15+2 15) = 1 day.

So it takes 3+3+1 = 7 days.

60% (1+2) = 20% of the apprentices completed in 3 days, which is also the amount completed by the master and apprentice in one day.

So a total of 3+3+1=7 days.

Cooperate for one day 20% Master ergonomics 40 3% Apprentice ergonomic efficiency 20 3% When the work is suspended for three days, the apprentice will do 20% and the remaining 20% will cooperate for one day A total of 3+3+1=7 days.

Today I am a little different, because I have to follow my parents to work for a day, so I have to get up an hour earlier than usual, and I am suffering from the rush hour bus congestion on the road, and I understand my parents' working environment for the first time, and I really feel the hardships of my parents.

My dad's job was very easy for everyone else, even my daughter. But today I'm going to change my mind about my dad's work. My dad was a small steel seller.

I went out with my father, and we went out at 5 o'clock in the morning to carry the bent branches, and we didn't come home until 7 or 8 o'clock in the evening to do more business. I can stand the weather in the morning, but at noon, I am like an ant on a hot pot, it is too hot, Dad is still outside to lift the steel plate, I can't even sit on the desk, not to mention that Dad is still outside, the sun has risen in mid-air, the dazzling light, the strong heat is still lifting the steel plate. I was so sad to see this.

Dad bought me a bottle of drink for four yuan, but he didn't buy it himself, so he drank the boiled water. At noon, Dad's meal is very simple, a plate of fried vegetables, a plate of roasted eggplant, in the past, my mother would come to my father to cook for him, but now my mother is not very comfortable, after all, Dad is a man, and cooking is a woman's job, so Dad's meal is so simple. But at home, I eat sweet meals every day, and I have a hard time swallowing these dishes.

But my dad bought a boxed lunch for me a few minutes ago. The uncle next to me saw me and said, "It's not easy for your father, he works hard, and he usually can't even buy a bottle of water!" It's all for you!

When you grow up, you must be filial to your father! "I grabbed the food in the lunch box, tears streaming down my eyes, and hurriedly turned my head away from them.

Dad got off work early for me. While eating dinner at home, I turned my face to look at my dad and noticed the pale white sideburns and shallow wrinkles on his forehead. Suddenly realized that Dad is usually too hard, and the hardships of life make him look old, Dad I love you.

I'm serious about coming in and seeing, what about the question! Oh, I forgot that the tomb ruler is still (omitted here), the process of seeing it has been, and that's it! I hope to help answer Wang Bei to you, I wish you to learn as much as possible!

Did you forget to post the question, or were you deliberately amusing people?

One. In case two. In the 11th year, 50,000 yuan is the annual payable before the core, and the annual interest rate of the remaining amount of the previous year is 5%, then the remaining amount of the previous year is = 350,000 yuan The remaining amount of the first year is 120-40 = 800,000 yuan Let this be the remaining amount of the banquet and the rough x year, then 80-5*(x-1) = 35x = 10, then the payment year is the year after the 10th year, that is, the 11th year.

The answer is 11th year.
