1. Expenditure: The customer bought 2 kilograms of beef, and the purchase price was 48/kg, so 2 kilograms of beef Master Jiang needed to spend 96 yuan

2. "Income": 36/kilogram of beef sold 4 kilograms (2 kilograms), and the income should be 36 * 4 = 144 yuan, but the customer gave 200 yuan of fake money, so the actual income was 0; However, Master Jiang needs to change the customer 200-144=56 yuan. So in the absence of income, another 56 yuan was spent.

3. Expenditure: Because Master Jiang exchanged 200 yuan with his neighbor with fake money and was found by his neighbor, he compensated his neighbor with 200 yuan, so he spent another 200 yuan.

To sum up, Master Jiang's total loss is 96 + 56 + 200 = 352 yuan.
