Considering only the fixed assets acquired as investing outflows:
Building 10,00,000 + Furniture 7,00,000 + Machinery 2,00,000 = 19,00,000 outflow.
The net cash used (outflow) from investing activities is Rs. 19,00,000.
Note: The question does not specify whether the investment in TATA shares and dividend received should be included in the final figure; based on the available options, only the fixed assets have been considered.
