Devendra is looking for getting his house painted. Getting the house painted will cost

Rs.150,000. The house has to be painted every 4th year (forever) and the cost of painting rises

by 4% every year (forever). His architect friend has suggested to him to get a wooden

panelling done instead which will last forever and require no maintenance. How much

Devendra should be willing to pay for the wooden panelling, given that he can earn 9% per

annum on his money.
