A. Given Machine A initial cost = RM 51,000
Annual cash flow = RM 10,500
Salvage value, S = RM 3,000
Life, n = 12 years
The IRR can be calculated by trial and error method. Let us assume IRR = 15%
P = 56,916.49 + 560.72
P = RM 57,477.21
The value is higher than RM 51,000 thus increase the IRR. Let us assume IRR = 20%
P =46,611.77 + 336.47
P = RM 46,948.23
Now we can determine the IRR through linear interpolation as follows.
IRR = 15 + 5*0.061517
IRR = 18.08%
Since, IRR is greater than MARR of 15%. Accept A.
Similarly for machine B we can calculate the IRR.
P = RM 27,000
A = RM 9,000
S = RM 900
N = 6 yrs
Let us assume IRR = 20%
P = 29,929.59 + 301.41
P = RM 30,231
Since it is greater than the value thus increase IRR. Let us assume IRR = 30%
P = 23,784.71 + 186.46
P = RM 23,971.16
Now using linear interpolation we can calculate IRR
IRR = 20 + 10*0.5161
IRR = 25.16% (Since, greater than MARR 15%) Accept.
Machine C.
When IRR = 20%
P = 9,000(PVIFA,20%,4) + 600(PVIF20%,4) = RM 23,987.96
Now assume IRR = 30%
P = 9000(PVIFA,30%,4)+600(PVIF,30%,4)
P = RM 19,706.24
IRR = 20 +(30-20)*(23,987.96-21,000)/(23,987.96-19,706.24)
= 20 + 10*2,987.96/4,281.72
= 20 + 10* 0.698
= 26.98% (Accept since greater than 15%)
Now, machine D.
The IRR = 0%
Reject machine D.
A. Machine C is most economical. Since its IRR is highest.
B. With a MARR of 20%
Machine A must be rejected. Since its IRR is less than MARR.
Machine B has an IRR of 25.07% Hence it can be selected.
Machine C has an IRR of 26.98% Hence it can be selected.
Machine D has IRR less than MARR so reject it.
Select machine C and B.

2. (a) Use Octave as a Calculator to answer this question. Suppose that A and B are two 8 × 9 matrices. The (i, j)-entry of the matrix B is given by i *j - 1. The (i,j)-entry of the matrix A equals 0 if i +j is divisible by and equals the (i,j)-entry of the matrix B otherwise. i. What are the rank and nullity of matrices A and B? ii. Is vector u- [9,...
