Answer

To solve the problem of how much three and a half dozen oranges cost when one orange costs two and a half rupees, we can follow these steps:

### Step 1: Understand the Cost of One Orange
The cost of one orange is given as 2.5 rupees.

### Step 2: Calculate the Total Number of Oranges
Three and a half dozen oranges means:
- One dozen = 12 oranges
- Three and a half dozen = 3.5 × 12 = 42 oranges

### Step 3: Calculate the Total Cost of Oranges
Now, we need to find the total cost for 42 oranges. We can do this by multiplying the number of oranges by the cost of one orange:
- Total cost = Number of oranges × Cost of one orange
- Total cost = 42 × 2.5

### Step 4: Perform the Multiplication
Now, we will calculate:
- 42 × 2.5 = 105 rupees

### Conclusion
Therefore, the total cost for three and a half dozen oranges is **105 rupees**.
