Answer:
NPV = 661468 – 728000 = -66532
Explanation:
Direct Material                          410
Direct Labour                           100
Variable manufacturing O/H Â Â Â Â Â Â Â Â Â Â Â Â Â Â 90
Variable cost to manufacture 1 unit           600
Loss on purchase component from outside supplier
(630 – 600) * 3000 units                  90000
(-) Contribution from released facility          10000
Operating Income would Decrease by        80000
Present Value of Future cash flow from Proposal X :-
PVAF for 5 years at 10% = 3.791
PVIF for 5th year at 10% = 0.621
PV of annual cash inflow (164000 * 3.791) Â Â Â Â 621724
PV of Residual value (64000 * 0.621) Â Â Â Â 39744
Present Value of Future cash flow      661468
NPV = 661468 – 728000 = -66532
