The new batch of children's clothes in kaixinbaobao children's clothing store is priced at 50 yuan per piece and sold at 75 yuan per piece. After selling 4 / 5 of the clothes, the profit is 15 yuan per piece. After all the clothes are sold out, the total profit is 3300 yuan. How many children's clothes are there in total?

Suppose there are x children's clothes in this batch
(75-50)×0.8x + (60-50)×0.2x = 3300
20x + 2x = 3300
22x = 3300
X = 150 pieces

What kind of numbers can be divided by 17 or 19

If the difference is a multiple of 17, the original number can be divided by 17. If the difference is too big or it is difficult to see whether it is a multiple of 17 by mental arithmetic, we need to continue the above process of "truncation, multiplication, subtraction and difference checking" until we can make a clear judgment

The feeling of reading the story of Beethoven (composition)

Today, I watched the biography of Beethoven in Zweig's biography of famous people. After reading this article, I got to know the music master Beethoven Ludwig and van Beethoven better. Beethoven was born in the attic of a shabby house in Bonn, near Cologne, on February 16, 1770. Beethoven's father was an unwieldy and drunken tenor, His mother is a servant, the child of a cook. Beethoven's childhood was hard, and he didn't enjoy the warmth of his family like Mozart. At the beginning, his life was a hard and cruel struggle. At the age of 20, he left his home and went out to make a living. When he came to the fore in the music industry, his ears were almost deaf, but he had to face the challenges, With his deep affection for music and superhuman talent, he created many famous Piano Sonatas and symphonies, and became a world-famous musician
As we all know, Beethoven was not only short and ugly, but also seriously ill. Later, he became deaf. However, the self respecting musician still believed, "no one can defeat me. I will hold the throat of fate."
In the sad days, Beethoven engaged in the cause of eulogizing joy. Only music can make him overcome his pain and drag him back from the edge of death again and again
In Beethoven's creative career, to overcome the bad fate, to overcome the mediocrity of mankind has always been his theme!
Ah! Beethoven is a man who never bows to his fate, perseveres, and is full of hope for the future. I think: we should carry forward Beethoven's spirit from childhood. We should not easily give in to fate. We must be full of confidence in the future. We should carry forward the spirit of hard work, courage to forge ahead, and not compromise to difficulties in our study, and strive to achieve excellent results in all aspects
Although people can't be judged by their appearance, it's really difficult for such a person to connect with the elegant art of music. But it is he who has become a great man in the history of music and made a great contribution to the history of human development
Beethoven's life can be compared with the great fictional tragedy. His hard childhood, failure of love, lack of money and loneliness can't stop him from marching to the palace of music and his infinite love for music. Maybe it's the envy of talent, or maybe it's the evil of previous life. In a word, for various reasons, the greater evil is ahead - injury, severe cold, lung disease, arthritis, Yellow fever and conjunctivitis seem to have been premeditated and tormented this great musician one after another. What's more, deafness. Deafness is only the death of a part of the world for ordinary people, and the death of the whole world for musicians
Beethoven was no exception. At the age of 32, he made a will, which in his own words was "liberated me from endless pain." maybe this is a way to extricate himself from the cruel fate, which can not be changed, at least can escape. But Beethoven's love for music's unruly power has overcome the human mediocrity, Conquered his own destiny, conquered his pain. He didn't believe in death
As a result, he rejected death and liberation again and again, and began the process of suffering. When the pain increased day by day, it accumulated until he could not bear it, and poured out like a tide, becoming a great work, the crystallization of his blood and tears
Every hero seems to have an unusual experience, and they all have to sacrifice for their own ideals. Beethoven even sacrificed from life to death. But with his love for art, the God above all else, and his unchanging ideals, Beethoven resolutely embarked on this road of no return. He exchanged pain for happiness
An unfortunate person, when poverty, disability and loneliness all attack him, when the world does not give him joy and voice, he creates joy to give to the world! Just like romanroland said, "without great character, there will be no great man, even no great artist, great actor." what I know is a great Beethoven
