You have OMR 12,000 in cash. You can deposit it today in a mutual fund earning 8.2 percent semiannually; or you can wait, enjoy some of it, and invest OMR 11,000 in your brother’s business in two years. Your brother is promising you a return of at least 10 percent on your investment. Whichever alternative you choose; you will need to cash in at the end of 10 years. Assume your brother is trustworthy and that both investments carry the same risk. Which one will you choose?
