2. Invest €100,000 for the next 2 years at an interest rate of 1.60% and then invest the proceeds for

3 years at an interest rate of 1.70%. Both deposits are compounded quarterly.

3. Invest €100,000 for the next 4 years at an interest of 1.90% and then use the proceeds to invest for 1 year at an interest of 0.80%. Both deposits are compounded monthly.

ii) Your father now tells you he has the option of investing for 5 years at an interest rate of 1.90% would he still select one of the 3 above options? (2 marks)

c. Ten thousand euro at the end of each of the first two years, starting one year from now; €15,000 at the end of each of the next four years; and €5,000 at the end of each of the last four years.

d. Ten thousand euro at the end of each of the next ten years, starting one year from now. Your relative points out that this option offers you the advantage of a steady cash flow.

1. €300,000 per year with first payment received immediately.

2. €500,000 per year at the end of the next three years.

3. A lump sum of €750,000 is received immediately and €75,000 every 6 months for the next 5 years.
