Question 3




3.1

Project 1:

= (R6 000 + R10 000 + R65 223 + R56 676 + R65 970) = R 203 869

= R202 022 – R203 869

Net Profit = R1 847

Project 2:

= (R5 540 + R90 000 + R101 098 + R78 902 + R80 426) = R355 966

= R355 966 - R317 250

Net profit = R38 716

Project 3:

= (R20 000 + R100 000 + R50 000 + R82 000 + R182 000) = R434 000

= R434 000 - R364 750

Net Profit = R69 250

3.2

Answer

Return on investment (ROI) - also called Accounting rate of return (ARR): Is a way of
comparing the net profitability to the investment required

= (average annual profit/Total investment) x 100

Project 1:

= ((R1 847/5)/202 022 x 100) = 0.18 %

Project 2:

= ((R38 716/5)/317 250 x 100) = 2.44%

Project 3:

= ((R69 250/5)/364 750 x 100) = 3.80%
