A representative of a financial institution offers you two alternative financial investments, namely Investment A and Investment B. If you go ahead with Investment A, you have to invest £5,000 now and you will receive £7,000 in 5 years' time. If you choose Investment B, you are required to invest £4,000 now and you will receive £7,000 in 6 years' time. Both investments are very safe because the financial institution is well-capitalised and reputable. Would you choose Investment A or Investment B?
