Answer:
option (A) 12%
Step-by-step explanation:
Data provided :
Purchasing cost of the machine = $ 22,712
Useful life of the machine = 5 years
Net annual cash inflow generated per year = $ 6,300
Now,
at for the value for internal rate of return,
the present value of inflow = Present value of the outflow for the 5 years
let the internal rate of return be r%
thus,
$ 22,712 =

on solving the above relation, we get
r ≈ 12%
Hence, option A is correct
