D. ?500

Answer

To solve the problem step by step, we will use the unitary method.

### Step 1: Find the cost of 1 orange
We know the cost of 24 oranges is Rs. 72. To find the cost of 1 orange, we divide the total cost by the number of oranges.

\[ \text{Cost of 1 orange} = \frac{\text{Total cost}}{\text{Number of oranges}} = \frac{72}{24} = 3 \]

### Step 2: Find the cost of 120 oranges
Now that we know the cost of 1 orange is Rs. 3, we can find the cost of 120 oranges by multiplying the cost of 1 orange by 120.

\[ \text{Cost of 120 oranges} = \text{Cost of 1 orange} \times \text{Number of oranges} = 3 \times 120 = 360 \]

### Final Answer
Therefore, the cost of 120 oranges is Rs. 360.
