The PC Company is considering adding a machine to its production line. The machine$$s base price is Rs $20000,$ and it would cost another Rs $5000$ to install it$.$ The machine falls into the depreciation of $3-$year class, and it would be sold after $3$ years for Rs $4500.$ The depreciation rates for the first $3$ years are $0\mathrm{.}2,0\mathrm{.}3,$ and $0\mathrm{.}4$ of the initial buying prices $($including machine base price $+$ installation cost$).$ The machine would require an increase in net working capital $($inventory$)$ of Rs$.5000$ for the whole life of the machine and working capital will not be recovered. The machine will generate a revenue of $14,000$ per year in before tax for the next three years. PC Company$$s marginal tax rate is $35\%.$ Would you like to buy the machine?
