answer correctly

5. For a piece of construction equipment mounted on pneumatic tires, find out the hourly ownership cost using average annual investment method with straight line depreciation from the following data; Initial cost = Rs.8000000, Estimated salvage value = Rs.1350000, Useful life of the equipment = 11 years, Cost of a set of tires = Rs.600000. The equipment will operate 1800 hours per year. The interest rate on investment is 7.5% per year. The annual rates for taxes, insurance and storage cost are 3%, 2.5% and 1% respectively. For this equipment, also calculate the hourly tire cost by not considering time value of money, if a new set of tires will be replaced at the end of every 4 years of operation and the estimated tire repair cost is 15% of straight-line depreciation.
