One day, Big Brother gave Bao Zheng ten pence to go shopping and buy meat. When he left, he specifically told Bao Zheng not to go to his second brother's shop to buy it, because his second brother was notoriously dirty and would definitely be short of weight. Bao Zheng heard about it and took to the streets. When his second brother saw Bao Zheng out shopping, he deliberately asked him Doby. In the second brother's mind, Bao Zheng is not only black, but also a little fool.
Bao Zheng thought, in this case, I will play a trick on my second brother today. So I told my second brother that he wanted to buy meat. The second brother said that a catty of pork belly with fat and thin is ten pence, and Bao Zheng said that a catty of pork belly with fat and thin is ok, but it costs half a catty. Half a catty of lean meat and half a catty of fat meat.
Since there are ten fatness and thinness, lean meat is definitely more expensive, six in a catty, and fat meat is cheaper, and four in a catty. He wants half a catty of lean meat and half a catty of fat meat, which adds up to five pence. The second brother was dizzy immediately after hearing this, so he gave him a catty of meat according to Bao Zheng's request.
Second brother still couldn't figure it out when he gave the meat. Usually this kind of meat costs ten pence a catty. Why is there only five pence here in Bao Zheng? What Bao Zheng said just now doesn't seem to be wrong, so what went wrong? Second brother didn't want to understand this problem when he went to Bao Zheng. Bao Zheng went home happily with meat.
Bao Zheng bought a catty of meat, although it was almost short, but it was a very cost-effective thing to buy it at half price. In fact, the second brother was bypassed by Bao Zheng. The unit price of a catty of lean meat should be twelve pence, and the unit price of a catty of fat meat is eight pence.
