D. `Rs. 112900`

Answer

To find the total amount of the bill for the chairs and blackboards purchased, we can follow these steps:

### Step 1: Calculate the total cost of the chairs.
- We know that the cost of each chair is Rs. 1065 and there are 50 chairs.
- To find the total cost of the chairs, we multiply the number of chairs by the cost of each chair.

\[ \text{Total cost of chairs} = \text{Number of chairs} \times \text{Cost per chair} \]
\[ \text{Total cost of chairs} = 50 \times 1065 \]
\[ \text{Total cost of chairs} = 53250 \]

### Step 2: Calculate the total cost of the blackboards.
- The cost of each blackboard is Rs. 1645 and there are 30 blackboards.
- To find the total cost of the blackboards, we multiply the number of blackboards by the cost of each blackboard.

\[ \text{Total cost of blackboards} = \text{Number of blackboards} \times \text{Cost per blackboard} \]
\[ \text{Total cost of blackboards} = 30 \times 1645 \]
\[ \text{Total cost of blackboards} = 49350 \]

### Step 3: Calculate the total amount of the bill.
- Now, we add the total cost of the chairs and the total cost of the blackboards to find the total bill.

\[ \text{Total bill} = \text{Total cost of chairs} + \text{Total cost of blackboards} \]
\[ \text{Total bill} = 53250 + 49350 \]
\[ \text{Total bill} = 102600 \]

### Final Answer:
The total amount of the bill is Rs. 102600.
