Problem 1
The cost of a project is $50,000 and it generates cash inflows of $20,000, $15,000, $25,000, and $10,000 over four years.
Required: Using the present value index method, appraise the profitability of the proposed investment, assuming a 10% rate of discount.
Solution
The first step is to calculate the present value and profitability index.

|
|
56,175 |
Total present value = $56,175
Less: initial outlay = $50,000
Net present value = $6,175
Profitability Index (gross) = Present value of cash inflows / Initial cash outflow
= 56,175 / 50,000
= 1.1235
Given that the profitability index (PI) is greater than 1.0, we can accept the proposal.
Net Profitability = NPV / Initial cash outlay
= 6,175 / 50,000 = 0.1235
N.P.I. = 1.1235 - 1 = 0.1235
Given that the net profitability index (NPI) is positive, we can accept the proposal.
Problem 2
A company is considering whether to purchase a new machine. Machines A and B are available for $80,000 each. Earnings after taxation are as follows:

Required: Evaluate the two alternatives using the following: (a) payback method, (b) rate of return on investment method, and (c) net present value method. You should use a discount rate of 10%.
Solution
(a) Payback method
24,000 of 40,000 = 2 years and 7.2 months
Payback period:
Machine A: (24,000 + 32,000 + 1 3/5 of 40,000) = 2 3/5 years.
Machine B: (8,000 + 24,000 + 32,000 + 1/3 of 48,000) = 3 1/3 years.
According to the payback method, Machine A is preferred.
(b) Rate of return on investment method
Particular |
Machine A |
Machine B |
Total Cash Flows |
1,36,000 |
1,44,000 |
Average Annual Cash Flows |
1,36,000 / 5 = $27,000 |
1,44,000 / 5 = $28,800 |
Annual Depreciation |
80,000 / 5 = $16,000 |
80,000 / 5 = $16,000 |
Annual Net Savings |
27,200 - 16,000 = $11,200 |
28,800 - 16,000 = $12,800 |
Average Investment |
80,000 / 2 = $40,000 |
80,000 / 2 = $40,000 |
ROI = (Annual Net Savings / Average Investments) x 100 |
(11,200 / 40,000) x 100 |
(12,800 / 40,000) x 100 |
|
= 28% |
= 32% |
According to the rate of return on investment (ROI) method, Machine B is preferred due to the higher ROI rate.
(c) Net present value method
The idea of this method is to calculate the present value of cash flows.

Net Present Value = Present Value - Investment
Net Present Value of Machine A: $1,04,616 - $80,000 = $24,616
Net Present Value of Machine B: $1,03,784 - 80,000 = $23,784
According to the net present value (NPV) method, Machine A is preferred because its NPV is greater than that of Machine B.
Problem 3
At the beginning of 2024, a business enterprise is trying to decide between two potential investments.
Required: Assuming a required rate of return of 10% p.a., evaluate the investment proposals under: (a) return on investment, (b) payback period, (c) discounted payback period, and (d) profitability index.

It is estimated that each of the alternative projects will require an additional working capital of $2,000, which will be received back in full after the end of each project.
Depreciation is provided using the straight line method. The present value of $1.00 to be received at the end of each year (at 10% p.a.) is shown below:
