Answer

To find the postal charges for booking a parcel of 1.8 kilograms, we can follow these steps:

### Step 1: Convert kilograms to grams
1. We know that 1 kilogram is equal to 1000 grams.
2. Therefore, to convert 1.8 kilograms to grams, we multiply:
\[ 1.8 \text{ kg} = 1.8 \times 1000 \text{ g} = 1800 \text{ g} \]

### Step 2: Find the cost per gram
1. We are given that the postal charges for 250 grams is Rs. 75.
2. To find the cost per gram, we divide the total cost by the weight in grams:
\[ \text{Cost per gram} = \frac{75 \text{ Rs}}{250 \text{ g}} = 0.3 \text{ Rs/g} \]

### Step 3: Calculate the total cost for 1800 grams
1. Now that we know the cost per gram, we can find the total cost for 1800 grams by multiplying the cost per gram by the total weight:
\[ \text{Total cost} = 1800 \text{ g} \times 0.3 \text{ Rs/g} = 540 \text{ Rs} \]

### Conclusion
