A. Cash flow from assets = Operating cash flow – Net capital spending – Net investment in marketable securities – Change in net working capitalOperating cash flow = PBIT – Taxes + Depreciation = 170 – 50 + 50 =

170Net capital spending = Ending net fixed assets – Beginning net fixed

Assets + depreciation = 550 – 495 + 50 = 105Net investment in = Ending Investments in marketable securities – Marketable securities beginning investment in marketable securities

= 30 – 25 = 5Change in net working = Ending net working capital – Beginning net Capital working capital = 205 – 195 = 10Cash flow from assets = 170 – 105 – 5 – 10 = 50Cash flow to lenders Interest – Net new borrowing = 35 – 20 = 15Cash flow to shareholders Dividend paid – Net new share capital raised =

1. A firm’s current assets and current liabilities are 1,600 and 1,000 respectively. How much can it borrow on a short- term basis without reducing the current ratio below 1.25?

Solution: Let the maximum short- term borrowing be B. The current ratio with this borrowing should be 1.25.

1,600+B1,000+B

=1.25

Solving this equation, we get B = 1,400. Hence the maximum permissible short -term borrowing is 1,400.

2. Determine the sales of a firm given the following information:Current ratio = 1.4Acid-test ratio = 1.2Current Liabilities = 1,600Inventory turnover ratio = 8

Solution: The sales figure may be derived as follows:Current assets = Current liabilities x Current ratio

= 1,600 x 1.4 = 2,240Current assets – Inventories = Current Liabilities x Acid -test ratio

= 1,600 x 1.2 – 1,920Inventories = 2,240 – 1,920 = 320Sales = Inventories x Inventories turnover ratio

= 320 x 8 = 2,560

3. The following ratios are given for Mintex CompanyNet profit margin ratio 4 percentCurrent ratio 1.25Return on net worth 15.23 percentTotal debt to total assets ratio 0.40Inventory turnover ratio 25

Complete the following statementsProfit and Loss Account

Rs. Sales Cost of goods sold Operating expenses 700 Profit before interest and tax Interest 45 Profit before tax

Page 5: Solved Problems

Tax provision (50 percent)Profit after tax

Balance SheetNet worth Fixed assetsLong-term debt Current Assets 180(10 percent interest)

CashShort-term debt Receivables 60(10.42 percent interest) Inventory

Solution: The blanks in the above statements may be filled as follows:(a) Short term debt: The value of short-term debt - the only current liabilities – is derived as

follows.

current ratio= Current assetsCurrent liabilities

=1.25

Current liabilities=Current assets1.25

= 1801.25

=144

So short-term debt is 144.(b) Long-term debt: The long-term debt carries 10 percent interest rate. Hence the long-

term debt is equal to Interest−.1042(144)

0.10=45−150.10

=300

(c) Total assets: As the ratio of total debt to total assets is 0.4, total assets (the total of the balance sheet) is simply:

Totaldebt0.4

=144+3000.4

=1110

(d) Net worth: The difference between total assets and total debt represents the net worth. Hence, it is equal to:

1100- (444) = 666(e) Fixed assets: The difference between total assets and current assets represents fixed

assets. So,Fixed assets = 1100 – 180 = 930

(f) Profit after tax: This is equal to: (Net worth) (Return on net worth) = (666) (0.1523) = 101.4

(g) Tax: As the tax rate is 50 percent, the tax provision is simply equal to the profit after tax, i.e., 101.4

Page 6: Solved Problems

(h) Profit before tax: The sum of the profit after tax and the tax provision is equal to the Profit before tax. So, it is equal to:

101.4 = 101.4 = 202.8(i) Profit before interest and taxes: This is equal to the profit before tax plus the interest

Payment. Hence, it is equal to:202.8 + 45 = 247.8

(j) Sales: The figure of the sales may be derived as follows:Profit after tax

Net profit marginratio=101.40.04

=2535

(k) Cost of goods sold: The figure of cost of goods sold may be derived from the following accounting identity:Sales – cost of goods sold – operating expenses = EBIT2535 – Cost of goods sold – 700 = 247.8Hence the cost of goods sold figure is 1587.2

(l) Inventory: This is equal to:Sales

Inventory turnover ratio=253525

=101.4

(m) Cash: This may be obtained as follows:Current assets – receivables – inventory = 180 – 60 – 101.4 =18.6

Page 9: Solved Problems

Debtors turnover = Net credit salesAverage debtors

= 1065(120+115) /2

=9.06

Average collection period = 365

Debtors turnover= 3659.06

=40.3days

Fixed assets turnover = Net sales

Average net fixesassets= 1065

(550+495)/2=2.04

Total assets turnover = Net sales

Average totalassets= 1065

(785+715)/2=1.42

Gross profit margin = Gross profitNet sales

= 2601065

(i) One of the important ratios considered by a bank for lending purposes is the ratio of the

total outside liabilities to tangible net worth. What is the ratio for ABC for the year

ended 31-3-X7?

(ii) List out the sources and uses of funds for the year ended 31-3-X7 classifying them under

the heads long-term and short-term.

(iii) Comment on the uses of funds based on the above.

Solution:

(i) Total outside liability = Public deposits + Debentures + Term loan + Trade creditors +

Short term bank borrowing + Provision for tax.

= 2000 + 17000 + 18000 + 10800 + 20000 + 2400 = 70200.

Tangible Networth = Equity shares + General reserve + Surplus – Miscellaneous

expenses

= 50000 + 14000 + 4800 – 10000 = 58800

Page 11: Solved Problems

The required ratio is: 70200/58800 = 1.19

(ii) Long-term sources Long-term uses

Net profit 4800 Purchase of fixes assets 12000

(Increase in reserve & surplus) Additional investments 2000

Depreciation for the year 5000 Repayment of public deposits 6000

Increase in debentures 2000 Repayment of term loan 2000

Addition to miscellaneous expenses 500

Total of long-term sources 11800 Total of long-term uses 22500

Short-term sources Short-term uses

Increase in trade creditors 2800 Increase in inventories 2000

Increase in bank borrowing 5000

Increase in provision for tax 400

Decrease in sundry debtors 4500

Total of short-term sources 12700 Total of short-term uses 2000

(iii) Long-term deficit = 22500 – 11800 = 10700

(iv) Short-term surplus = 12700 – 2000 = 10700

ABC has diverted short-term funds amounting to 10700 raised mainly by resorting to

additional market credit and increased short-term bank borrowing, for long-term uses

like purchase of fixed assets and repayment of public deposits which is not prudent.

2. The following information is available for Olympus Limited: A/S = 0.8, ∆S = Rs. 20

million, L/S = 0.40, m = 0.06, S1 = Rs. 100 million and d = 0.4. What is the external funds

requirement for the forthcoming year?

Solution:

The external funds requirement of Olympus is:

EFR = A*/SO (∆ S) – L*/ S (∆ S) – mS1(r)

= 0.8 x 20 – 0.4 x 20 – 0.6 x 100 x 0.6

Page 17: Solved Problems

= Rs. 4.4 million

3. The following information is available for Signal Corporation: m = 0.05, d = 0.30, A/E =

2.4, A/So = 1.0. What rate of growth can be sustained with internal equity?

Solution:

The sustainable growth rate for Signal is:

g=m(So/ Ao)(1+D /E)b1−m (So /Ao ) (1+D /E )b

= 0.05 x1 x2.4 x 0.71−0.05 x1 x2.4 x 0.7

= 9.17 percent.

1. If you invest Rs. 5,000 today at a compound interest of 9 percent, what will be its future

value after 75 years?

Solution: The future value of Rs. 5,000 after 75 years, when it earns a compound

interest of 9 percent is

Rs. 5,000 (1.09)75

Since the FVIF table given in Appendix A has a maximum period of 30, the future value

expression may be stated as

Page 18: Solved Problems

Rs. 5,000 (1.09)30 (1.09)30 (1.09)15

The above product is equal to

Rs. 5,000 (13.268) (13.268) (3.642) = Rs. 32, 05,685.1

2. If the interest rate is 12 percent, what are the doubling periods as per the rule of 72 and

the rule of 69 respectively?

Solution: As per the rule of 72 the doubling period will be

72/12 = 6 years

As per the rule of 69, the doubling period will be

0.35 + 6912

=6.1 years

3. A borrower offers 16 percent nominal rate of interest with quarterly compounding.

What is the effective rate of interest?

Solution: The effective rate of interest is

(1+0.164 )4 - 1 = (1.04)4 – 1

= 1.17 – 1

= 0.17 = 17 percent

4. Fifteen annual payments of Rs. 5,000 are made into a deposit account that pays 14

percent interest per year. What is the future value of this annuity at the end of 15

years?

Solution: The future value of this annuity will be:

Rs. 5,000 (FVIFA14%, 15) = Rs. 5,000 (43.842) = Rs. 2, 19,210

5. A finance company advertises that it will pay a lumpsum of Rs. 44,650 at the end of five

years too investors who deposit annually Rs. 6,000 for 5 years. What is the interest rate

implicit in this offer?

Solution: The interest rate may be calculated in two steps

(a) Find the FVIFA for this contract as follows:

Rs. 6,000 (FVIFA) = Rs. 44,650

So

Page 19: Solved Problems

FVIFA = Rs . 44.650Rs.6,000

=7.442

(b) Look at the FVIFA table and read the row corresponding to 5 years until 7.442 or a

value close to it is reached. Doing so we find that

FVIFA20%,5yrs is 7.442

So, we conclude that the interest rate is 20 percent.

6. What is the present value of Rs. 1,000,000 receivables 60 years from now, if the

discount rate is 10 percent?

Solution: The present value is

Rs. 1,000,000 (11.10 )60

This may be expressed as

Rs. 1,000,000 (11.10 )30 (

11.10 )30

= Rs. 1,000,000 (0.057) (0.057) = Rs. 3249

7. A 12 – payment annuity of Rs. 10,000 will begin 8 years hence. (The first payment occurs

at the end of 8 years.) What is the present value of this annuity if the discount rate is 14

percent?

Solution: This problem may be solved in two steps.

Step 1: Determine the value of this annuity a year before the first payment begins i.e., 7

years from now. This is equal to:

Rs. 10,000 (PVIFA14%,12years) = Rs. 10,000 (5.660)

= Rs. 56,600

Step 2: Compute the present value of the amount obtained in Step 1:

Rs. 56,600 (PVIFA14%,7years) = Rs. 56,600 (0.400)

= Rs. 22,640

8. What is the present value of the following cash stream if the discount rate is 14

percent?

Year 0 1 2 3 4

Cash flow 5,000 6,000 8,000 9,000 8,000

10. You want to take a world tour which costs Rs. 1,000,000 – the cost is expected to remain

unchanged in nominal terms. You are willing to save annually Rs. 80,000 to fulfill your

desire. How long will you have to wait if your savings earn a return of 14 percent per

annum?

Solution: The future value of an annuity of Rs. 80,000 that earns 14 percent is Equated

to Rs. 1,000,000.

80,000 x FVIFAn=?,14% = 1,000,000

80,000 (1,14n−10.14 ) = 1,000,000

1.14n – 1 = 1,000,00080,000 x 0.14 = 1.75

1.14n – 1 = 1.75 + 1 = 2.75

n log 1.14 = log 2.75

n x .0569 = 0.4393

n = 0.4393/0.0569 = 7.72 years

You will have to wait for 7.72 years

11. Shyam borrows Rs. 80,000 for a musical system at a monthly interest of 1.25 percent.

The loan is to be repaid in 12 equal monthly instalments, payable at the enf of each

month. Prepare the loan amortization schedule.

Solution:

The monthly installment A is obtained by solving the equation:

80,000 = A x PVIFAn=12,r=1.25%

80,000 = A x 1− 1

(1+r )nr

80,000 = A x 1− 1

(1.0125)12.0125

= A x 11.0786

Hence A = 80,000 / 11.0786 = Rs. 7221

The loan amortization schedule is shown below:
