Answer:

Let's calculate the profit or loss for each item and then find the overall result.

1. **Rice:**

- Selling price for 100 kg of rice at a profit of ₹15 per kg = \(100 \, \text{kg} \times ₹15/\text{kg}\)

2. **Pulses:**

- Selling price for 50 kg of pulses at a loss of ₹20 per kg = \(50 \, \text{kg} \times (-₹20)/\text{kg}\) (negative since it's a loss)

3. **Milk:**

- Selling price for 20 liters of milk at a loss of ₹5 per liter = \(20 \, \text{L} \times (-₹5)/\text{L}\) (negative for the loss)

Now, add these three amounts to find the overall profit or loss:

\[ \text{Total} = (\text{Rice profit}) + (\text{Pulses loss}) + (\text{Milk loss}) \]

Calculate the result in rupees.

Answer

Rice: Profit of 15 per kg * 100 kg = 1500

Pulses: Loss of 20 per kg * 50 kg = -1000

Milk: Loss of 5 per litre * 20 L = -100

Now, add these values to find the overall profit or loss:

1500 - 1000 - 100 = 400

The farmer incurs a profit of 400 rupees.
