Master Wang sells fish, and a kilo of fish costs 46 yuan. At present, the market price is special for 35 yuan. The customer bought a kilogram and gave Master Wang fake money 100 yuan. Master Wang had no change, so he asked his neighbor to change it for 100 yuan. Afterwards, neighbors found that the money was fake during the process of saving money, and it was confiscated by the bank. Master Wang also lost 100 to his neighbor. How much did Master Wang lose?

Answer:

There is no gain or loss between Master Wang and his neighbors. Pay the price in 0 yuan first, get the change of 100 yuan, and then pay it back.

Customers pay fake money worth 0 yuan to get fish worth 46 yuan, and the change is 30 yuan (100-35×2=30), and * * * is 76 yuan.

So Master Wang lost 76 yuan.
