PART A [Total : 60 marks] Please use the answer sheet provided. QUESTION 1 a) Find the present value of an income stream that has a negative flow of RM100 per year for 3 years, a positive flow of RM200 in the 4th year, and a positive flow of RM300 per year in Years 5 through 8. The appropriate discount rate is 4% for each of the first 3 years and 5% for each of the later years. Thus, a cash flow accruing in Year 8 should be discounted at 5% for some years and 4% in other years. All payments occur at year-end.

He assumes that the cost of one year of health care for a college student is RM1,000 today, that the average student is 18 when he or she enters college, that inflation in health care cost is rising at the rate of 10% per year, and that parents can save RM100 per year to help cover their children’s costs. All payments occur at the end of the relevant period, and the RM100/year savings will stop the day the child enters college (hence 18 payments will be made). Savings can be invested at a nominal rate of 6%, annual compounding. Rahman wants a health care plan that covers the fully inflated cost of health care for a student for 4 years, during Years 19 through 22 (with payments made at the end of Years 19 through 22). How much would the government have to set aside now (when a child is born), to supplement the average parent’s share of a child’s college health care cost? The lump sum the government sets aside will also be invested at 6%, annual compounding. [10 marks] c) You are saving for the college education of your two children. One child will enter college in 5 years, while the other child will enter college in 7 years. College costs are currently RM10,000 per year and are expected to grow at a rate of 5% per year.
