Answer and Explanation:
The computation of the present value index for each proposal is shown below:
As we know that
NPV = Cash inflow Present Value - Cash outflow Present Value
That means
Present Value of future cash inflows = NPV + Present Value of Cash Outflow
For Proposal X ,
Future cash inflows Present Value = $172000 ($27,000 + $145,000)
And,
Future cash outflows Present Value = $145,000
So,
Present Value Index is
= $172000 ÷ $145,000
= 1.18
For Proposal Y ,
Future cash inflows Present Value = $320000 ($40,000 + $280,000)
Future cash outflows Present Value = $280,000
So,
Present Value Index is
= $172,000 ÷ $145,000
= 1.14
So proposal X is more profitable.
