The price increase reserve technology should be the project cost, assuming that the project cost is 20 million, the investment in the first year is100000, and the investment in the second year is100000.

The reserve fund for price increase in the first year is1000 * (1+10%)-1=1ten thousand.

The reserve fund for price increase in the second year is1000 * (1+10%) 2-1= 265438+million.

Therefore, the reserve fund for price increase should be 100+265438+ ten thousand yuan.
