The third question: One of the companies built and erected an irrigation pumping station consisting of five pumps. The price of one pump is 1,000,000 (one million dinars) and its life span is (15) years, with a residual value of (15%) of the remaining value of the buildings, which amounts to (200,000) two hundred thousand dinars, noting that the constructions It took (3) years at an amount of (65%) of the project cost of (80,000,000) eighty million dinars. These constructions will be destroyed within (25) years. Calculate the amount of depreciation in the tenth year of the project and the remaining book value for each of the pumps and buildings using the three methods.
