Explanation:
Please find attached the diagram of the cash flows
Internal rate of return is the discount rate that equates the after-tax cash flows from an investment to the amount invested
IRR = (future value / present value)^(1/n)
n = number of years
1. (2637/1100)^(1/11) - 1 = 8.27
2. (13091 / 9500)^(1/7) - 1 = 4.69
3. (1855 / 400)^(1/15) - 1 = 10.77
4. (5030 / 3200)^(1/5) - 1 = 9.47
5. (9598 / 6000)^(1/10) - 1 = 4.81
