PT WIRABANGSA is considering two mutually exclusive projects namely Project A and Project B. Both projects require the same initial outlay of $500,000 and have the same economic life of 5 years. In depreciation using the straight-line method. The salvage value of project A is $60,000 while that of project B is $80,000. The expected net profit (EAT) from the two projects is as follows:

Years	Proyek A	Proyek B
1	$ 112.000	$ 146.000
2	$ 112.000	$ 166.000
3	$ 112.000	$ 176.000
4	$ 112.000	$ 156.000
5	$ 72.000	$ 66.000

The certainty equivalent coefficient ( t ) for net cash flows is as follows:

Years	Proyek A	Proyek B
1	0,964	0,946
2	0,929	0,896
3	0,895	0,848
4	0,862	0,802
5	0,831	0,759

The average interest rate for government bank deposits is 6%, Beta for project A is 0.8 and project B is 1.2, while the market rate of return is 11%.

Question : a. Calculate the NPV using the Certainty Equivalent Method of the two projects. b. Calculate the NPV using the RADR Method of the two projects. c. In your opinion which project should be chosen.
