Assume that an industrial building can be purchased for 1,5000,000 today, is expected to yield cash flows of 80,000 for each of the next five years (with the cash flows occurring at the end of each year), and can be sold at the end of the fifth year for 1,600,000. Calculate the internal rate of return (IRR) for this transaction.

1. (a) 5.0%
2. (b) 6.5%
3. (c) 9.5%
4. (d) 10.0%
