QUESTION 1 Consider the ollowing cash ow diagrams In these d
Solution
Future value is always larger than present value as interest is added in future value.
Let’s consider the cash flow as $ 1,000 per year and calculate PV and FV of annuities.
Calculation of PV:
PV = C x [1-(1+r)-n/r]
C = Cash flow per period = $ 1,000
r = Rate per period = 8 % = 0.08
n = Numbers of periods = 7
PV = $ 1,000 x [1- (1 + 0.08)-7 /0.08]
= $ 1,000 x [1- (1.08)-7 /0.08]
= $ 1,000 x [(1- 0.58349) /0.08]
= $ 1,000 x (0.41651 /0.08)
= $ 1,000 x 5.20637
= $ 5,206.37
Calculation of FV:
FV = C x [(1+r)n - 1 /r]
Putting the same values as above, we get
FV = $ 1,000 x [(1+0.08)7 – 1/0.08]
= $ 1,000 x [(1.08)7 – 1/0.08]
= $ 1,000 x [(1.713824 – 1/0.08]
= $ 1,000 x (0.713824/0.08)
= $ 1,000 x 8.922803
= $ 8,922.80
We also observed from the above calculation that FV of annuity is greater than PV of annuity.
Hence option “P is less than F” is correct answer.
