You want to evaluate your savings of 1.000.000 TL. If you deposit your money in the bank, you get 10% interest income in every two years. The Bank also provides 7% annual income to the 4-year private account and 9% annual income to the 6-year private account. Also, if you invest your money in a 6-year government bond, 7.5% per year; if you invest in a 8-year municipal bond, you can get 9.5% interest income per year. However, the government deducts 15% tax in every two years from the interest income you get from the bank and 12% tax in every year from municipal bond. How should you invest 1.000.000 TL to maximize the earnings at the end of 10 years
