Aunt, did the paper money with 6000 yuan in the tin can rust and corrode after the heavy rain?
Speaking of this matter, Wu Yuqing, a teller of a bank in Wangjiang, has a deep memory. A few days ago, an aunt in her fifties walked into the business hall of the branch with a bag. This aunt is Aunt Wang. After greeting Aunt Wang to sit down, Xiao Wu asked her purpose. Aunt Wang handed the bag to her hand and said excitedly, "Accountant, help me change the money." Xiao Wu opened the bag and instantly understood what Aunt Wang meant by changing money. It turned out that the bag contained damaged coins with a face value of 100 yuan, which was several thousand yuan. Common coins are basically worn or washed, but this bag of banknotes looks rusty and should be corroded by rust. What is the reason? After Xiao Wu asked Aunt Wang, it turned out that Aunt Wang put 6000 yuan in cash in an iron can and buried it in the vegetable garden next to her house. Recently, because of the rainy weather, she was a little worried about getting wet, so she dug out the tin can for inspection. This investigation startled Aunt Wang, because the money in the jar was corroded by rust to varying degrees! Looking at a jar of broken coins, Aunt Wang was a little at a loss. Fortunately, the neighbor told her that she could take the broken coins to the rural commercial bank and change them into complete coins, which reassured her and immediately came to the bank with the money.
Xiao Wu carefully sorted out the broken coins one by one, carefully pasted them on white paper and pieced them together one by one. It was found that only 565,438+0 sheets reached the convertibility standard, and the other 9 sheets were too corroded, all of them were broken into two pieces, which could not be distinguished and could not meet the convertibility requirements. After Xiao Wu's patient explanation, Aunt Wang approved the exchange confirmation result and finally exchanged 5 100 yuan. After the exchange was completed, Aunt Wang did not choose to bring cash back, but put the money in her social security card. Xiao Wu learned from Aunt Wang's words that Aunt Wang didn't keep the money in the bank because she was afraid that her husband would secretly take it away with her ID card and passbook.
