An industrial organization studying the relative desirability of two diesel engines proposed for installation has estimated that the annual operating costs for engine A is Tk. 40,000 and for engine B is Tk. 35000. What is the added justifiable investment for engine B if the cost of money use is 8 percent of the investment, taxes are 4 percent of 80 percent of the first cost, insurance is 0.3 percent of investment, and annual depreciation charge has been set at 5 percent of the total investment?
