Multiple choice

What is the formula for calculating the present value of a single cash flow?

  1. PV = CF / (1 + r)^n

  2. PV = CF * (1 + r)^n

  3. PV = CF * r^n

  4. PV = CF / r^n
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The formula for calculating the present value of a single cash flow is PV = CF / (1 + r)^n, where PV is the present value, CF is the cash flow, r is the discount rate, and n is the number of years.

Multiple choice

What is the formula for calculating the internal rate of return (IRR) of a project?

  1. IRR = (CF1 + CF2 + ... + CFn) / (Initial investment)

  2. IRR = (CF1 * (1 + r)^n + CF2 * (1 + r)^(n-1) + ... + CFn) / (Initial investment)

  3. IRR = (CF1 / (1 + r)^n + CF2 / (1 + r)^(n-1) + ... + CFn / (1 + r)) / (Initial investment)

  4. IRR = (CF1 + CF2 + ... + CFn) / (Initial investment * (1 + r)^n)

Multiple choice

A farmer is considering two different loan options, A and B. Loan A has an interest rate of 5% and a repayment period of 10 years. Loan B has an interest rate of 6% and a repayment period of 5 years. If the farmer needs to borrow $100,000, which loan should the farmer choose?

  1. Loan A

  2. Loan B

  3. Both loans have the same total cost

  4. Cannot be determined from the given information
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The total cost of Loan A is $100,000 * (1 + 0.05)^10 - $100,000 = $162,889.46. The total cost of Loan B is $100,000 * (1 + 0.06)^5 - $100,000 = $133,822.58. Therefore, Loan A has the lower total cost and should be chosen by the farmer.

Multiple choice

What is the formula for calculating the Future Worth of a project?

  1. FW = P * (F/P, i%, n)

  2. FW = A * (F/A, i%, n)

  3. FW = P * (A/P, i%, n)

  4. FW = A * (P/A, i%, n)

Multiple choice

The Fisher Equation states that the nominal interest rate (i) is equal to the sum of the real interest rate (r) and the expected inflation rate (π). Express this relationship mathematically.

  1. i = r + π

  2. i = r - π

  3. i = r / π

  4. i = r * π
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Fisher Equation is expressed as i = r + π, where i is the nominal interest rate, r is the real interest rate, and π is the expected inflation rate.

Multiple choice

If the nominal interest rate is 5% and the expected inflation rate is 2%, what is the real interest rate?

  1. 3%

  2. 7%

  3. 10%

  4. 12%
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Using the Fisher Equation, i = r + π, we can solve for the real interest rate: r = i - π. Substituting the given values, we get r = 5% - 2% = 3%.
