9 You are given a choice between Plan 1: $2,000 a year from now and $1,000 in two years OR Plan 2: $1,000 a year from now and $2,000 in two years. The interest rate is the same in both plans. Which has the higher PV ?
(A) Plan 1
(B) Plan 2
(C) Plans 1 and 2 are equivalent
(D) It depends on the interest rate

investments have a 10% return ?
(A) 10%
(B) At least $1,000
(C) A negative number

11 A project has an NPV of $1,250 at 10%. If you were to calculate the
projects IRR, you should get a number bigger than 10% ?
True False
12 A project has an NPV of $1,250 at 10%. If you were to calculate the
Project’s PI, will you get a number bigger than 1 ?
Yes No

business are $2.5 million, operating costs of $1.5 million, a marginal
tax rate of 45% and depreciation of $1 million?

(B) $750k
(C) $1 million
(D) $1.25 million
14 For the information in problem 13. If the revenue for the business increase and everything else stays the same, you would expect the after tax cash flow to:
(A) Increase
(B) Decrease
15 For the information in problem 14. If the operating costs go up for the business increase and everything else stays the same, you would expect the after tax cash flow to:
(A) Increase
(B) Decrease

(A) Increase
(B) Decrease
17 A project has an investment of $10,000. It returns $250 in each of the
next 40 years ! You are to do an IRR calculation. As you know the calculation involves trial and error. Is a good first guess at the IRR given by IRR = $250/$10,000 = 2.5% ?
Yes No
18 A project has an investment of $1000 and returns of $300 in each of
years 1, 2, 3 and 4. A reasonable estimate of the IRR is (Hint: Use the tables in the back of the book):
