__It is the difference between the Actual Sales and the Sales at the Break-even point. Larger Margin of safety indicates stronger business. Such business can continue to earn profits, even if sales decrease (i.e. in recession). Thus,__

**margin of Safety:**Margin of Safety (in Rs.) = Actual Sales – BEP Sales (Rs.)

Margin of safety (in units) = Actual Sales(units) – BEP Sales (in units)

- S. Ltd. furnishes you the following information relating to the half year ending 30
^{th}September 2007. Fixed expenses Rs.50,000, sales value Rs.2,00,000 and Profit Rs.50,000. During the second half of the same year the company, has projected a loss of Rs.10,000. Calculate:- PV ratio, break-even point and margin of safety for six months ending 30
^{th}September 2007. - Expected sales volume for second half of the year assuming that selling price and fixed expenses remain unchanged in the second half year also.
- The break-even point and margin of safety of the whole year 2007-08.

- A retail dealer in garments is currently selling 24,000 shirts
annually. He supplies the following details for the year ended 31
^{st}December 2007.

General office costs for the year Rs.80,000

Advertising costs for the year Rs.40,000.

As a management accountant of the firm, you are required to answer each of the following independently.

- Calculate the BEP and margin of safety in sales revenue and number of shirts sold.
- Assume that 20,000 shirts were sold in a year. Find out the net profit of the firm.
- If it is decided to introduce selling commission of Rs.3 per shirt, how many would require to be sold in a year to earn a net income of Rs.15,000.

- Present the following information to show to the management
- The marginal product cost and the contribution per unit.
- The total contribution and profits resulting from each of the following sales mixtures:

Product Rs. Per Unit

Direct materials A 10

B 9

Direct wages A 3

B 2

Fixed expenses Rs.800

Variable expenses are allocated to products as 100% of direct wages.

Sales price A 20

B 15

Sales mixtures:

i. 1000 units of product A and 2000 units of B

ii. 1500 units of product A and 1500 units of B

iii. 2000 units of product A and 1000 units of B

Which product mix is most profitable?

- The following particulars are extracted from the records of a company:

Product A Product B

Sales Rs.100 Rs.120

Consumption of raw materials 2 Kg. 3 Kg.

Material Cost Rs.10 Rs.15

Direct Wages Cost Rs.15 Rs.10

Direct Expenses Rs.5 Rs.6

Machine hours used 3hrs. 2hrs.

Overhead expenses:

Fixed Rs.15 Rs.10

Variable Rs.15 Rs.20

Direct Wages per hour is Rs.5. Comment on the profitability of each product (both products need the same raw materials) when:

i. Total sales potentials in units is limited.

ii. Total sales potential in value is limited.

iii. Raw materials are in short supply.

iv. Production capacity (in terms of machine hours) is the limiting factor.

Assuming raw materials as the key factor, availability of which is 10,000 kg. and maximum sales potential of each product being 3,500 units, find the product mix which will yield the maximum profit.

- A company produces a single product which is sold by it presently in the domestic market at Rs.75 per unit. The present production and sales is 40,000 units per month representing 50% of the capacity available. The cost data of the product are as under:
