Answer

To solve the problem, we need to calculate the total cost of 1.5 dozen oranges and 1.5 kg of apples.

### Step 1: Calculate the cost of 1.5 dozen oranges
1. **Determine the number of oranges in 1.5 dozen**:
\[ 1.5 \text{ dozen} = 1.5 \times 12 = 18 \text{ oranges} \]

2. **Calculate the cost of 18 oranges**:
\[ \text{Cost of 1 orange} = 5.50 \text{ rupees} \]
\[ \text{Total cost for 18 oranges} = 18 \times 5.50 = 99 \text{ rupees} \]

### Step 2: Calculate the cost of 1.5 kg of apples
1. **Determine the cost of 1.5 kg of apples**:
\[ \text{Cost of 1 kg apple} = 80 \text{ rupees} \]
\[ \text{Total cost for 1.5 kg apples} = 1.5 \times 80 = 120 \text{ rupees} \]

### Step 3: Calculate the total cost
1. **Add the costs of oranges and apples**:
\[ \text{Total cost} = \text{Cost of oranges} + \text{Cost of apples} \]
\[ \text{Total cost} = 99 + 120 = 219 \text{ rupees} \]

### Final Answer:
The total cost of 1.5 dozen oranges and 1.5 kg of apples is **219 rupees**.
