MARKET AND DEMAND ANALYSIS
1. We have to estimate the parameters a and b in the linear relationshipYt= a + bT
Using the least squares method.According to the least squares method the parameters are:
T Yn T Yb =
T2 n T2
a = YbTThe parameters are calculated below:

THE TIME VALUE OF MONEY
1. Value five years hence of a deposit of Rs.1,000 at various interest rates is asfollows:
r = 8% FV5 = 1000 x FVIF (8%, 5 years)= 1000 x 1.469 = Rs.1469
r = 10% FV5 = 1000 x FVIF (10%, 5 years)= 1000 x 1.611 = Rs.1611
r = 12% FV5 = 1000 x FVIF (12%, 5 years)= 1000 x 1.762 = Rs.1762
r = 15% FV5 = 1000 x FVIF (15%, 5 years)= 1000 x 2.011 = Rs.2011
2. Rs.160,000 / Rs. 5,000 = 32 = 25
According to the Rule of 72 at 12 percent interest rate doubling takes placeapproximately in 72 / 12 = 6 years
So Rs.5000 will grow to Rs.160,000 in approximately 5 x 6 years = 30 years
3. In 12 years Rs.1000 grows to Rs.8000 or 8 times. This is 23 times the initialdeposit. Hence doubling takes place in 12 / 3 = 4 years.
According to the Rule of 69, the doubling period is:
0.35 + 69 / Interest rate
Equating this to 4 and solving for interest rate, we get
Interest rate = 18.9%.
4. Saving Rs.2000 a year for 5 years and Rs.3000 a year for 10 years thereafter isequivalent to saving Rs.2000 a year for 15 years and Rs.1000 a year for the years6 through 15.
Hence the savings will cumulate to:
2000 x FVIFA (10%, 15 years) + 1000 x FVIFA (10%, 10 years)= 2000 x 31.772 + 1000 x 15.937 = Rs.79481.

5. LetA be the annual savings.
A x FVIFA (12%, 10 years) = 1,000,000A x 17.549 = 1,000,000
So A = 1,000,000 / 17.549 = Rs.56,983.
6. 1,000 x FVIFA (r, 6 years) = 10,000
FVIFA (r, 6 years) = 10,000 / 1000 = 10
From the tables we find that
FVIFA (20%, 6 years) = 9.930FVIFA (24%, 6 years) = 10.980
Using linear interpolation in the interval, we get:
20% + (10.000 9.930)
r= x 4% = 20.3%(10.980 9.930)
7. 1,000 x FVIF (r, 10 years) = 5,000FVIF (r,10 years) = 5,000 / 1000 = 5
From the tables we find thatFVIF (16%, 10 years) = 4.411
FVIF (18%, 10 years) = 5.234
Using linear interpolation in the interval, we get:
(5.000 4.411) x 2% r= 16% + = 17.4%
(5.234 4.411)
8. The present value of Rs.10,000 receivable after 8 years for various discount rates(r) are:r= 10% PV = 10,000 x PVIF(r= 10%, 8 years)
= 10,000 x 0.467 = Rs.4,670
r= 12% PV = 10,000 x PVIF (r= 12%, 8 years)= 10,000 x 0.404 = Rs.4,040
r= 15% PV = 10,000 x PVIF (r= 15%, 8 years)
7/31/2019 Projects Solutions Pfa
10/89
= 10,000 x 0.327 = Rs.3,2709. Assuming that it is an ordinary annuity, the present value is:
2,000 x PVIFA (10%, 5years)= 2,000 x 3.791 = Rs.7,582
10. The present value of an annual pension of Rs.10,000 for 15 years when r= 15%is:
10,000 x PVIFA (15%, 15 years)= 10,000 x 5.847 = Rs.58,470
The alternative is to receive a lumpsum of Rs.50,000.
Obviously, Mr. Jingo will be better off with the annual pension amount ofRs.10,000.
11. The amount that can be withdrawn annually is:100,000 100,000
A = ------------------ ------------ = ----------- = Rs.10,608PVIFA (10%, 30 years) 9.427
12. The present value of the income stream is:
1,000 x PVIF (12%, 1 year) + 2,500 x PVIF (12%, 2 years)+ 5,000 x PVIFA (12%, 8 years) x PVIF(12%, 2 years)
= 1,000 x 0.893 + 2,500 x 0.797 + 5,000 x 4.968 x 0.797 = Rs.22,683.
13. The present value of the income stream is:
2,000 x PVIFA (10%, 5 years) + 3000/0.10 x PVIF (10%, 5 years)= 2,000 x 3.791 + 3000/0.10 x 0.621= Rs.26,212
14. To earn an annual income of Rs.5,000 beginning from the end of 15 years fromnow, if the deposit earns 10% per year a sum of
Rs.5,000 / 0.10 = Rs.50,000
is required at the end of 14 years. The amount that must be deposited to get thissum is:
Rs.50,000 / PVIF (10%, 14 years) = Rs.50,000 / 3.797 = Rs.13,165
7/31/2019 Projects Solutions Pfa
11/89
15. Rs.20,000 =- Rs.4,000 x PVIFA (r, 10 years)PVIFA (r,10 years) = Rs.20,000 / Rs.4,000 = 5.00
From the tables we find that:
PVIFA (15%, 10 years) = 5.019PVIFA (18%, 10 years) = 4.494
Using linear interpolation we get:
5.019 5.00r= 15% + ---------------- x 3%
5.019 4.494= 15.1%
16. PV (StreamA) = Rs.100 x PVIF (12%, 1 year) + Rs.200 xPVIF (12%, 2 years) + Rs.300 x PVIF(12%, 3 years) + Rs.400 xPVIF (12%, 4 years) + Rs.500 x PVIF (12%, 5 years) +Rs.600 x PVIF (12%, 6 years) + Rs.700 x PVIF (12%, 7 years) +
Rs.800 x PVIF (12%, 8 years) + Rs.900 x PVIF (12%, 9 years) +Rs.1,000 x PVIF (12%, 10 years)
= Rs.100 x 0.893 + Rs.200 x 0.797 + Rs.300 x 0.712+ Rs.400 x 0.636 + Rs.500 x 0.567 + Rs.600 x 0.507+ Rs.700 x 0.452 + Rs.800 x 0.404 + Rs.900 x 0.361+ Rs.1,000 x 0.322

Similarly,PV (StreamB) = Rs.3,625.2PV (Stream C) = Rs.2,851.1
17. FV5 = Rs.10,000 [1 + (0.16 / 4)]5x4

20. Investment required at the end of 8th year to yield an income of Rs.12,000 peryear from the end of 9th year (beginning of 10th year) for ever:
Rs.12,000 x PVIFA(12%, )= Rs.12,000 / 0.12 = Rs.100,000
To have a sum of Rs.100,000 at the end of 8th year , the amount to be depositednow is:
Rs.100,000 Rs.100,000
= = Rs.40,388PVIF(12%, 8 years) 2.476
21. The interest rate implicit in the offer of Rs.20,000 after 10 years in lieu ofRs.5,000 now is:
Rs.5,000 x FVIF (r,10 years) = Rs.20,000
Rs.20,000FVIF (r,10 years) = = 4.000
Rs.5,000
From the tables we find thatFVIF (15%, 10 years) = 4.046
This means that the implied interest rate is nearly 15%.I would choose Rs.20,000 for 10 years from now because I find a return of 15%
quite acceptable.
22. FV10 = Rs.10,000 [1 + (0.10 / 2)]10x2
= Rs.10,000 (1.05)20
= Rs.10,000 x 2.653= Rs.26,530
If the inflation rate is 8% per year, the value of Rs.26,530 10 years from now, in
terms of the current rupees is:
7/31/2019 Projects Solutions Pfa
13/89
Rs.26,530 x PVIF (8%,10 years)= Rs.26,530 x 0.463 = Rs.12,283
23. A constant deposit at the beginning of each year represents an annuity due.
PVIFA of an annuity due is equal to : PVIFA of an ordinary annuity x (1 + r)
To provide a sum of Rs.50,000 at the end of 10 years the annual deposit should be
Rs.50,000A = FVIFA(12%, 10 years) x (1.12)
Rs.50,000= = Rs.2544
17.549 x 1.12
24. The discounted value of Rs.20,000 receivable at the beginning of each year from2005 to 2009, evaluated as at the beginning of 2004 (or end of 2003) is:
Rs.20,000 x PVIFA (12%, 5 years)= Rs.20,000 x 3.605 = Rs.72,100.
The discounted value of Rs.72,100 evaluated at the end of 2000 is
Rs.72,100 x PVIF (12%, 3 years)= Rs.72,100 x 0.712 = Rs.51,335
IfA is the amount deposited at the end of each year from 1995 to 2000 thenA x FVIFA (12%, 6 years) = Rs.51,335A x 8.115 = Rs.51,335A = Rs.51,335 / 8.115 = Rs.6326
25. The discounted value of the annuity of Rs.2000 receivable for 30 years, evaluatedas at the end of 9th year is:
Rs.2,000 x PVIFA (10%, 30 years) = Rs.2,000 x 9.427 = Rs.18,854
The present value of Rs.18,854 is:Rs.18,854 x PVIF (10%, 9 years)
= Rs.18,854 x 0.424= Rs.7,994
26. 30 percent of the pension amount is0.30 x Rs.600 = Rs.180
Assuming that the monthly interest rate corresponding to an annual interest rate of12% is 1%, the discounted value of an annuity of Rs.180 receivable at the end of
each month for 180 months (15 years) is:
7/31/2019 Projects Solutions Pfa
14/89
Rs.180 x PVIFA (1%, 180)
(1.01)180 - 1Rs.180 x ---------------- = Rs.14,998
.01 (1.01)180
If Mr. Ramesh borrows Rs.Ptoday on which the monthly interest rate is 1%
P x (1.01)60 = Rs.14,998P x 1.817 = Rs.14,998
Rs.14,998P = ------------ = Rs.8254
1.817
27. Rs.300 x PVIFA(r, 24 months) = Rs.6,000
PVIFA (4%,24) = Rs.6000 / Rs.300 = 20
From the tables we find that:
PVIFA(1%,24) = 21.244PVIFA (2%, 24) = 18.914
Using a linear interpolation
21.244 20.000r = 1% + ---------------------- x 1%
21.244 18,914
= 1.53%Thus, the bank charges an interest rate of 1.53% per month.The corresponding effective rate of interest per annum is
[ (1.0153)12 1 ] x 100 = 20%
28. The discounted value of the debentures to be redeemed between 8 to 10 yearsevaluated at the end of the 5th year is:
Rs.10 million x PVIF (8%, 3 years)+ Rs.10 million x PVIF (8%, 4 years)+ Rs.10 million x PVIF (8%, 5 years)= Rs.10 million (0.794 + 0.735 + 0.681)= Rs.2.21 million
IfA is the annual deposit to be made in the sinking fund for the years 1 to 5, thenA x FVIFA (8%, 5 years) = Rs.2.21 millionA x 5.867 = Rs.2.21 million
A = 5.867 = Rs.2.21 million
7/31/2019 Projects Solutions Pfa
15/89
A = Rs.2.21 million / 5.867 = Rs.0.377 million
29. Let n be the number of years for which a sum of Rs.20,000 can be withdrawnannually.
Rs.20,000 x PVIFA (10%, n) = Rs.100,000PVIFA (15%, n) = Rs.100,000 / Rs.20,000 = 5.000
From the tables we find thatPVIFA (10%, 7 years) = 4.868PVIFA (10%, 8 years) = 5.335
Thus n is between 7 and 8. Using a linear interpolation we get
5.000 4.868n = 7 + ----------------- x 1 = 7.3 years
5.335 4.868
30. Equated annual installment = 500000 / PVIFA(14%,4)= 500000 / 2.914= Rs.171,585

31. Define n as the maturity period of the loan. The value of n can be obtained fromthe equation.
200,000 x PVIFA(13%, n) = 1,500,000PVIFA (13%, n) = 7.500
From the tables or otherwise it can be verified that PVIFA(13,30) = 7.500
Hence the maturity period of the loan is 30 years.

Simplifying the above equation we getr = 1.61, -0.61; (or) 161%, (-)61%
Note : Given two changes in the signs of cashflow, we get two values for theIRR of the cashflow stream. In such cases, the IRR rule breaks down.

The pay back period of the project lies between 2 and 3 years. Interpolating inthis range we get an approximate pay back period of 2.63 years.
Project N
The pay back period lies between 1 and 2 years. Interpolating in this range weget an approximate pay back period of 1.55 years.

Cost of capital = 12% per annum
7/31/2019 Projects Solutions Pfa
24/89
NPV = Rs.20.63 million
Since the two projects are independent and the NPV of each project is (+) ve,both the projects can be accepted. This assumes that there is no capitalconstraint.
(d) ProjectMCost of capital = 10% per annumNPV = Rs.25.02 million
Project N
Cost of capital = 10% per annumNPV = Rs.23.08 million
Since the two projects are mutually exclusive, we need to choose the projectwith the higher NPV i.e., choose projectM.
Note : The MIRR can also be used as a criterion of merit for choosing betweenthe two projects because their initial outlays are equal.
(e) Project MCost of capital = 15% per annumNPV = 16.13 million
Project N
Cost of capital:15% per annumNPV = Rs.17.23 million
Again the two projects are mutually exclusive. So we choose the project with thehigher NPV, i.e., choose projectN.
(f) ProjectMTerminal value of the cash inflows: 114.47MIRR of the project is given by the equation
50 (1 + MIRR)4 = 114.47
i.e., MIRR = 23.01%Project N
Terminal value of the cash inflows: 115.41MIRR of the project is given by the equation
50 ( 1+ MIRR)4 = 115.41i.e., MIRR = 23.26%

THE COST OF CAPITAL
1(a) Define rD as the pre-tax cost of debt. Using the approximate yield formula, rDcan be calculated as follows:
14 + (100 108)/10
7/31/2019 Projects Solutions Pfa
34/89
rD = ------------------------ x 100 = 12.60%0.4 x 100 + 0.6x108
(b) After tax cost = 12.60 x (1 0.35) = 8.19%
2. Define rp as the cost of preference capital. Using the approximate yield formularp can be calculated as follows:
9 + (100 92)/6rp = --------------------
0.4 x100 + 0.6x92
= 0.1085 (or) 10.85%
3. WACC= 0.4 x 13% x (1 0.35)+ 0.6 x 18%
= 14.18%
4. Cost of equity = 10% + 1.2 x 7% = 18.4%(using SML equation)Pre-tax cost of debt = 14%After-tax cost of debt = 14% x (1 0.35) = 9.1%Debt equity ratio = 2 : 3WACC = 2/5 x 9.1% + 3/5 x 18.4%
= 14.68%
5. Given0.5 x 14% x (1 0.35) + 0.5 x rE = 12%
where rE is the cost of equity capital.Therefore rE 14.9%Using the SML equation we get
11% + 8% x = 14.9%where denotes the beta of Azeezs equity.
Solving this equation we get = 0.4875.
6 (a) The cost of debt of 12% represents the historical interest rate at the time the debtwas originally issued. But we need to calculate the marginal cost of debt (costof raising new debt); and for this purpose we need to calculate the yield tomaturity of the debt as on the balance sheet date. The yield to maturity will notbe equal to 12% unless the book value of debt is equal to the market value ofdebt on the balance sheet date.

(b) The cost of equity has been taken asD1/P0 ( = 6/100) whereas the cost of equityis (D1/P0) + gwhere grepresents the expected constant growth rate in dividendper share.

8.
(a) GivenrD x (1 0.3) x 4/9 + 20% x 5/9 = 15%rD = 12.5%,where rD represents the pre-tax cost of debt.
(b) Given13% x (1 0.3) x 4/9 + rE x 5/9 = 15%rE = 19.72%, where rErepresents the cost of equity.
9. Cost of equity = D1/P0 +g
= 3.00 / 30.00 + 0.05= 15%
(a) The first chunk of financing will comprise of Rs.5 million of retained earningscosting 15 percent and Rs.25 million of debt costing 14 (1-.3) = 9.8 percent.The second chunk of financing will comprise of Rs.5 million of additionalequity costing 15 percent and Rs.2.5 million of debt costing 15 (1-.3) = 10.5percent.
(b) The marginal cost of capital in the first chunk will be :5/7.5 x 15% + 2.5/7.5 x 9.8% = 13.27%The marginal cost of capital in the second chunk will be :
5/7.5 x 15% + 2.5/7.5 x 10.5% = 13.50%
Note : We have assumed that(i) The net realisation per share will be Rs.25, after floatation costs, and(ii) The planned investment of Rs.15 million is inclusive of floatation costs

10. The cost of equity and retained earningsrE = D1/PO +g
= 1.50 / 20.00 + 0.07 = 14.5%
The cost of preference capital, using the approximate formula, is :11 + (100-75)/10
rE = = 15.9%0.6x75 + 0.4x100
The pre-tax cost of debentures, using the approximate formula, is :13.5 + (100-80)/6
rD = = 19.1%0.6x80 + 0.4x100
The post-tax cost of debentures is19.1 (1-tax rate) = 19.1 (1 0.5)
= 9.6%The post-tax cost of term loans is
12 (1-tax rate) = 12 (1 0.5)= 6.0%

Assumptions: (1) The useful life is assumed to be 10 years under all threescenarios. It is also assumed that the salvage value of theinvestment after ten years is zero.
(2) The investment is assumed to be depreciated at 10% perannum; and it is also assumed that this method and rate ofdepreciation are acceptable to the IT (income tax)authorities.
(3) The tax rate has been calculated from the given table i.e. 10/ 35 x 100 = 28.57%.
(4) It is assumed that only loss on this project can be offsetagainst the taxable profit on other projects of the company;and thus the company can claim a tax shield on the loss inthe same year.

Standard deviation = (PIj - PI)2Pjo fP1 j=1

The standard deviation ofP1 is .1075 for the given investment with an expectedPI of 1.24. The maximum standard deviation of PI acceptable to the company
for an investment with an expected PI of 1.25 is 0.30.
Since the risk associated with the investment is much less than the maximumrisk acceptable to the company for the given level of expected PI, the companyshould accept the investment.

2. (i) Since there are 3 securities, there are 3 variance terms and 3 covariance terms.Note that if there are n securities the number of covariance terms are: 1 + 2 ++
(n + 1) = n (n 1)/2. In this problem all the variance terms are the same (2A) allthe covariance terms are the same (AB) and all the securities are equally weighted( wA = )
So,
2p = [3 w2A 2A + 2 x 3 AB]2p = [3 w2A 2A + 6 wA wB AB]
1 2 1 1
= 3 x x 2A + 6 x x x AB3 3 3
1 2
= 2A + AB3 3
(ii) Since there are 9 securities, there are 9 variance terms and 36 covarianceterms. Note that if the number of securities is n, the number of covarianceterms is n(n 1)/2.
In this case all the variance terms are the same (2A), all the covariance terms are1
the same (AB) and all the securities are equally weighted wA =9
So,n(n-1)
2p = 9 w2A 2A t 2 x wA wB AB2

Cov (RB,RM) = = = 16.84n 1 19
(RMRM)2 1186

So the beta for stockB is:16.84
= 0.27062.42
4. According to the CAPM, the required rate of return is:
E(Ri) =Rf+ (E(RMRf)i
Given a risk-free rate (Rf) of 11 percent and the expected market risk premium(E(RMRf) of 6 percent we get the following:
Project Beta Required rate(%) Expected rate (%)A 0.5 11 + 0.5 x 6 = 14 15B 0.8 11 + 0.8 x 6 = 15.8 16C 1.2 11 + 1.2 x 6 = 18.2 21D 1.6 11 + 1.6 x 6 = 20.6 22E 1.7 11 + 1.7 x 6 = 21.2 23
a. The expected return of all the 5 projects exceeds the required rate as per the CAPM.
So all of them should be accepted.b. If the cost of capital of firm which is 16 percent is used as the hurdle rate, project A
will be rejected incorrectly.
5. The asset beta is linked to equity beta, debt-equity ratio, and tax rate as follows:
EA =
[1 +D/E(1 T)]
The asset beta of A, B, and C is calculated below:
Firm Asset Beta
1.25A = 0.49
[1 + (2.25) x 0.7]
1.25
B = 0.48[1 + (2.00) x 0.7]
1.10C = 0.45
[1 + (2.1) x 0.7]
7/31/2019 Projects Solutions Pfa
53/89
0.49 + 0.48 + 0.45Average of the asset betas of sample firms = = 0.47
3The equity beta of the cement project is
E= A [ 1 +D/E(1 T)]= 0.47 [1 + 2 (1-0.3)] = 1.128
As per the CAPM model, the cost of equity of the proposed project is:12% + (17% - 12%) x 1.128 = 17.64%
The post-tax cost of debt is:16% (1 0.3) = 11.2%
The required rate of return for the project given a debt-equity ratio of 2:1 is:1/3 x 17.64% + 2/3 x 11.2% = 13.35%
6. EA =
[1 +D/E(1 T)]E = 1.25 D/E= 1.6 T= 0.3
So, Pariman Companys asset beta is:1.25
= 0.59[1 + 1.6 (0.7)]
7. (a) Asset beta for a petrochemicals project is:
E 1.30A = =
[1 +D/E( 1 T)] [1 + 1.5 (1 .4)]
= 0.68
The equity beta (systematic risk) for the petrochemicals project of Growmore,whenD/E= 1.25 and T= 0.4, is
0.68 [1 + 1.25 (1 .4)] = 1.19
7/31/2019 Projects Solutions Pfa
54/89
(b) The cost of equity for the petrochemicals project is12% + 1.19 (18% - 12%) = 19.14%
The cost of debt is
12% (1 0.4) = 7.2%Given, a debt equity ratio of 1.25 the required return for the petrochemicals
project is1 1.25
19.14% x + 7% x = 12.4%2.25 2.25

6. Presently a 9 unit building yields a profit of Rs.1.8 million (9 x 1.2 9) and a 15 unitbuilding yields a profit of Rs.1.0 million (15 x 1.2 17). Hence a 9 unit building isthe best alternative if the builder has to construct now.
However, if the builder waits for a year, his payoffs will be as follows:
Market Condition
Alternative Buoyant (Apartment price:Rs.1.5 million)
Sluggish (Apartment price:Rs.1.1million)
9 unit building 1.5 x 9 9 = 4.5 1.1 x 9 9 = 0.9
15 unit building 1.5 x 15 17 = 5.5 1.1 x 15 17 = -0.5
Thus, if the market turns out to be buoyant the best alternative is the 15 unitbuild
