8 Operating Costing
BASIC CONCEPTS AND FORMULAE Basic Concepts 1. Operating Costing: It is a method of ascertaining costs of providing or operating a
service. This method of costing is applied by those undertakings which provide services rather than production of commodities.
2. Cost units: Transport service − Passenger km., quintal km., or tonne km. Supply service − Kw hr., Cubic metre, per kg., per litre. Hospital − Patient per day, room per day or per bed, per operation
etc. Canteen − Per item, per meal etc. Cinema − Per ticket. Composite units i.e. tonnes kms., quintal kms. etc. may be computed in two ways. 3.. Multiple Costing: It refers to the method of costing followed by a business wherein
a large variety of articles are produced, each differing from the other both in regard to material required and process of manufacture. In such cases, cost of each article is computed separately by using, generally, two or more methods of costing.
Basic Formulas 1. Absolute (weighted average) tonnes-kms: Absolute tonnes-kms., are the sum total of tonnes-kms., arrived at by multiplying
various distances by respective load quantities carried. 2. Commercial (simple average) tonnes-kms : Commercial tonnes-kms., are arrived at by multiplying total distance kms., by
average load quantity.

8.2 Cost Accounting
Question 1 A Mineral is transported from two mines – 'A' and 'B' and unloaded at plots in a Railway Station. Mine A is at a distance of 10 kms, and B is at a distance of 15 kms. from railhead plots. A fleet of lorries of 5 tonne carrying capacity is used for the transport of mineral from the mines. Records reveal that the lorries average a speed of 30 kms. per hour, when running and regularly take 10 minutes to unload at the railhead. At mine 'A' loading time averages 30 minutes per load while at mine 'B' loading time averages 20 minutes per load. Drivers' wages, depreciation, insurance and taxes are found to cost ` 9 per hour operated. Fuel, oil, tyres, repairs and maintenance cost ` 1.20 per km. Draw up a statement, showing the cost per tonne-kilometer of carrying mineral from each mine.

Question 2 EPS is a Public School having 25 buses each plying in different directions for the transport of its school students. In view of large number of students availing of the bus service, the buses work two shifts daily both in the morning and in the afternoon. The buses are garaged in the school. The workload of the students has been so arranged that in the morning, the first trip picks up senior students and the second trip plying an hour later picks up junior students. Similarly, in the afternoon, the first trip takes the junior students and an hour later the second trip takes the senior students home. The distance travelled by each bus, one way is 16 kms. The school works 24 days in a month and remains closed for vacation in May and June. The bus fee, however, is payable by the students for all the 12 months in a year. The details of expenses for the year 2003-2004 are as under: Driver's salary – payable for all the 12 in month. ` 5,000 per month per drive. Cleaner's salary payable for all the 12 months `3,000 per month per cleaner (one cleaner has been employed for every five buses). Licence Fees, Taxes etc. ` 2,300 per bus per annum Insurance Premium ` 15,600 per bus per annum Repairs and Maintenance ` 16,400 per bus per annum Purchase price of the bus ` 16,50,000 each Life of the bus 16 years Scrap value ` 1,50,000 Diesel Cost ` 18.50 per litre Each bus gives an average of 10 kms per litre of diesel. The seating capacity of each bus is 60 students. The seating capacity is fully occupied during the whole year. The school follows differential bus fees based on distance traveled as under:

8.12 Cost Accounting
Answer
(i) Total equivalent single room suites
Nature of suite Occupancy Equivalent single room suites
Single room suites 100 × 360 × 100% = 36,000 36,000 × 1 = 36,000 Double rooms suites 50 × 360 × 80% = 14,400 14,400 × 2.5 = 36,000 Triple rooms suites 30 × 360 × 60% = 6,480 6,480 × 5 = 32,400 Total 1,04,400
(ii) Statement of total cost:
(`) Staff salaries 14,25,000 Room attendant’s wages 4,50,000 Lighting, heating and power 2,15,000 Repairs and renovation 1,23,500 Laundry charges 80,500 Interior decoration 74,000 Sundries 1,53,000 25,21,000 Building rent 10,000 × 12 + 5% on total taking 1,20,000 + 5% on takings Total cost 26,41,000 + 5% on total takings
Profit is 20% of total takings ∴ Total takings = ` 26,41,000 + 25% of total takings Let x be rent for single room suite Then 1,04,400 x = 26,41,000 + 25% of (1,04,400 x) or 1,04,400 x = 26,41,000 + 26,100 x or 78,300 x = 26,41,000 or x = 33.73
(ii) Rent to be charged for single room suite = ` 33.73 Rent for double rooms suites ` 33.73 × 2.5 = ` 84.325
Rent for triple rooms suites ` 33.73 × 5 = ` 168.65

Answer Operating Costing: It is method of ascertaining costs of providing or operating a service. This method of costing is applied by those undertakings which provide services rather than production of commodities. This method of costing is used by transport companies, gas and water works departments, electricity supply companies, canteens, hospitals, theatres, schools etc. Composite units may be computed in two ways: (a) Absolute (weighted average) tones kms, quintal kms etc. (b) Commercial (simple average) tones kms, quintal kms etc. Absolute tonnes-kms are the sum total of tonnes kms arrived at by multiplying various distances by respective load quantities carried. Commercial tonnes-kms, are arrived at by multiplying total distance kms, by average load quantity.

Questions for Practice
1. Distinguish between Operating Costing and Operation Costing. Answer: Refer to ‘Chapter No. 6 i.e. Method of Costing I’ of Study Material. 2. (a) What do you understand by Operating Costs? Describe its essential features and state where it can
be usefully implemented. (b) A chemical factory runs its boiler on furnace oil obtained from Indian Oil and Bharat Petroleum, whose
depots are situated at a distance of 12 and 8 miles from the factory site. Transportation of Furnace Oil is made by the Company's own tank lorries of 5 tons capacity each. Onward trips are made only on full load and the lorries return empty. The filling-in time takes an average 40 minutes for Indian Oil and 30 minutes for Bharat Petroleum. But the emptying time in the factory is only 40 minutes for all. From the record available it is seen that the average speed of the company's lorries works out to 24 miles per hour. The varying operating charges average 60 paise per mile covered and fixed charges give an incidence of ` 7.50 per hour of operation. Calculate the cost per ton mile for each source.
Answer: (a) Refer to ‘Chapter No. 6 i.e. Method of Costing I’ of Study Material. (b) Indian Oil Bharat Petroleum
Cost per ton mile 53 paise (Approx.) 58.00 paise (Approx)

3. SMC is a public school having five buses each plying in different directions for the transport of its school students. In view of a large number of students availing of the bus service, the buses work two shifts daily both in the morning and in the afternoon. The buses are garaged in the school. The work-load of the students has been so arranged that in the morning the first trip picks up the senior students and the second trip plying an hour later picks up the junior students. Similarly in the afternoon the first trip drops the junior students and an hour later the second trip takes the senior students home.
The distance travelled by each bus one way in 8 kms. The school works 25 days in a month and remains closed for vacation in May, June and December. Bus fee, however, is payable by the students for all the 12 months of the year.
The details of expenses for a year are as under: Driver's salary ` 450 per month per driver Cleaner's salary ` 350 per month (Salary payable for 12 months) (One cleaner employed for all the five buses)
