A water treatment system has been installed in a community at a cost of Rs. 5,20,000. Assuming the life of the system as 15 years, work out the amount of annual instalment of sinking fund required to accumulate the whole amount at 4% interest. The sinking fund factor at 4% interest for 15 year = 0.05; and the capital recovery factor at 4% for 15 year = 0.09 respectively. Assume a Scrap value of Rs. 20,000 for the system after 15 years.
