1. Calculate the present value for the cost of RM 10,000 which will be spent for 20 years if the interest: (i) 15% per year. (ii) 15% per year compounded two times a year. 2. Assume that you save RM 1,000 for year 0, 2, 4, 6, 8, 10 and your saving will get an interest of 8% per year compounded every half a year. (0) Calculate the total saving at the end of year 10? (ii) Calculate the present value of the saving
