A cooling water pumping station at a manufacturing plant in Iligan City costs 30,000,000 php to construct, and it is projected to have a 25-year life with an estimated salvage value of 10% of the construction cost. Calculate the annual depreciation charge for year 10 (d10) using:

a. Straight Line Method

b. Declining Balance Method

c. Double declining balance method

d. Sinking Fund method at 10%

e. Sum of the year’s digits method

2. If the cooling water pumping station in Problem 1 will be book-depreciated to zero over a recovery period of 30 years, calculate year 10 (d10) manually using the double declining balance method.
