The purchase price of one pound of beef is 48 yuan, and Master Jiang, just four pounds of beef will lose 48 yuan multiplied by four pounds of ***192 yuan. In addition, I also found change for others, 56 yuan, so to speak, other customers, took 200 yuan of fake money, exchanged for beef and change, a *** worth 248 yuan. The 248 yuan was paid by Master Jiang, did he pay for anything else?

Yes! He exchanged 200 yuan of fake money for his neighbor's 200 yuan of real change, and used 56 yuan to give change and had 144 left in his hand, at this time the neighbor's money was confiscated by the bank, and he came back to him to ask for 200 yuan of real money. At this time, does Master Jiang still have 200 money in his hand? No, he still has 144 yuan left after the change, and he needs to pay another 56 yuan out of his pocket to make up enough 200 to pay back the neighbor's money.

So Master Jiang lost 192 yuan of beef money and 56 yuan of change, and another 56 yuan of rounding. A *** loss of 304 yuan
