1. Initial Plant Purchase:
On 1st April 2007, the limited company purchased a small plant for Rs. 100,000. This purchase would be recorded as a fixed asset in the company's balance sheet. The plant's cost would be capitalized and recorded as an asset on the balance sheet, and the corresponding amount would be deducted from the company's cash or bank balance.

2. Additional Plant Purchase:
On 1st October 2007, the company purchased another plant for Rs. 50,000. Similar to the first purchase, this plant's cost would also be capitalized and recorded as a fixed asset on the balance sheet. The company's cash or bank balance would be reduced by the amount paid for the plant.

3. Impact on Financial Statements:
The purchases of these plants would have the following impact on the company's financial statements:

a. Balance Sheet:

- Cash or Bank Balance: The cash or bank balance would be reduced by the total amount paid for the plants.

b. Income Statement:
The purchases of the plants would not directly impact the income statement. However, the depreciation expense associated with the plants would be recorded as an expense on the income statement over the expected useful life of the plants.

c. Cash Flow Statement:
The purchases of the plants would be classified as cash outflows from investing activities on the cash flow statement. The amount paid for the plants would be deducted from the cash flow from operating activities.

Conclusion:
The limited company's purchase of a small plant on 1st April 2007 for Rs. 100,000 and an additional plant on 1st October 2007 for Rs. 50,000 would have a significant impact on the company's financial statements.
