$2\mathrm{.}1.$ Calculate the difference between the following investment proposals:

Investment A: R $1,000$ invested annually for five successive years at $10\%$ per annum.

Investment B: R $2,051\mathrm{.}85$ invested for $5$ years at $20\%$ per annum compound interest. $(5)$

$2\mathrm{.}2.$ Calculate the present value of $R25,000$ received annually for $10$ successive years using a discount rate of $16\%?$

$2\mathrm{.}3$ You are to receive an amount of R$1,7008$years from now. However, if you could have received the amount right now and invested it you would have been able to earn interest at $8\%$ per annum on the amount. What would the amount be worth if you could receive it now instead of waiting eight years?

$2\mathrm{.}4.R10,000$ is invested in a savings account at $20\%$ per annum compound interest for $10$ years. Calculate the end value of the investment?

$2\mathrm{.}5.$ You invest R $3,600$ per year for $10$ successive years $($at the end of each year$)$ in a savings account at $15\%$ per annum compound interest. What will be the end value in the savings account?
