Let's solve this question.
00:02
Here we have given a year, a project a and here the project b.
00:07
So here year that is 0, 1, 2, 3, 4 and 5 and here project a that is $5000, minus $5000, 2750, 2750, 2750, 2750 and 2750.
00:26
Now here project b that is minus 9000, 1000, 3000, 5000, 7000, 9000.
00:38
So here we in this question in the part a we need to find what which project should be selected if the simple payback method is used to make the determination.
00:51
So therefore here first of all for this part a we need to find the cumulative cash flow for project a and then for project b.
01:07
So here for project a it is minus 5000, minus 2250 and here it is 5000.
01:15
Here minus 9000, minus 8000 and minus 5000.
01:21
So here payback period for project a that is equals to year that is 1 plus cash flow required in the payback year divided by the total cash flow in the year.
01:41
So that the total cash flow in the payback year.
01:45
So that is equals to 1 plus in bracket 2750 minus 2250 that will be divided by 2750.
01:54
So that is equals to we will get 1 .18 years and here the payback for project b that is equals to year prior to backpack that is 2 plus here cash flow required in the backpack year that is 5000 divided by the total.
02:13
So that is also 5000.
02:15
So that is equals to 3 years.
02:16
So here we can say that project a should be selected based on the payback period at as it has the lower payback period when compared to b.
02:37
Now here in the part b we need to find which project should be selected if npv were used at 10 % interest.
02:48
So here we can say that for the pvf for 10 % here it is for c it is 1 0 .90909 0 .82645 0 .75131 0 .68301 and 0 .62092.
03:16
Now here the pva pv of cash flow of project a and then that of project b...
