Operating Costing Question 1 Distinguish between Operating Costing and Operation Costing. Answer (1) Operating Costing: It is a method of costing applied by undertakings which provide service rather than production of commodities. Like unit costing and process costing, operating costing is thus a form of operation costing. The emphasis under operating costing is on the ascertainment of cost of rendering services rather than on the cost of manufacturing a product. It is applied by transport companies, gas and water works, electricity supply companies, canteens, hospitals, theatres, school etc. Within an organisation itself certain departments too are known as service departments which provide ancillary services to the production departments. For example, maintenance department; power house; boiler house; canteen; hospital; internal transport. Operation Costing: It represent a refinement of process costing. In this each operation instead of each process of stage of production is separately costed. This may offer better scope for control. At the end of each operation, the unit operation cost may be computed by dividing the total operation cost by total output. Question 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 Rs. 7.50 per hour of operation. Calculate the cost per ton mile for each source.

Operating Costing

Question 1 Distinguish between Operating Costing and Operation Costing.

Answer (1) Operating Costing: It is a method of costing applied by undertakings which provide service rather than production of commodities. Like unit costing and process costing, operating costing is thus a form of operation costing. The emphasis under operating costing is on the ascertainment of cost of rendering services rather than on the cost of manufacturing a product. It is applied by transport companies, gas and water works, electricity supply companies, canteens, hospitals, theatres, school etc. Within an organisation itself certain departments too are known as service departments which provide ancillary services to the production departments. For example, maintenance department; power house; boiler house; canteen; hospital; internal transport. Operation Costing: It represent a refinement of process costing. In this each operation instead of each process of stage of production is separately costed. This may offer better scope for control. At the end of each operation, the unit operation cost may be computed by dividing the total operation cost by total output. Question 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 Rs. 7.50 per hour of operation. Calculate the cost per ton mile for each source.

Cost Accounting 9.2

Answer (a) Operating Costs are the costs incurred by undertakings which do not manufacture any

product but provide a service. Such undertakings for example are — Transport concerns, Gas agencies; Electricity Undertakings; Hospitals; Theatres etc. Because of the varied nature of activities carried out by the service undertakings, the cost system used is obviously different from that followed in manufacturing concerns.

The essential features of operating costs are as follows: (1) The operating costs can be classified under three categories. For example in the

case of transport undertaking these three categories are as follows: (a) Operating and running charges. It includes expenses of variable nature. For

example expenses on petrol, diesel, lubricating oil, and grease etc. (b) Maintenance charges. These expenses are of semi-variable nature and

includes the cost of tyres and tubes, repairs and maintenance, spares and accessories, overhaul, etc.

(c) Fixed or standing charges. These includes garage rent, insurance, road licence, depreciation, interest on capital, salary of operating manager, etc.

(2) The cost unit used is a double unit like passenger-mile; Kilowatt-hour, etc. It can be implemented in all firms of transport, airlines, bus-service, etc., and by all firms of Distribution Undertakings. (b) Statement showing the cost per ton mile of carrying furnace oil from Indian Oil

Question 3 Write short note on operation costing. (May, 1996, 4 marks)

Answer Operation Costing: It is defined as the refinement of process costing. It is concerned with the determination of the cost of each operation rather than the process. In those industries where a process consists of distinct operations, the method of costing applied or used is called operation costing. Operation costing offers better scope for control. It facilitate the computation of unit operation cost at the end of each operation by dividing the total operation cost by total input units. It is the category of the basic costing method, applicable, where standardized goods or services result from a sequence of repetitive and more or less continuous operations, or processes to which costs are charged before being averaged over the units produced during the period. The two costing methods included under this head are process costing and service costing. Question 4 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.

Cost Accounting 9.4

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 Rs. 450 per month per driver Cleaner's salary Rs. 350 per month (Salary payable for 12 months) (One cleaner employed for all the five buses)

License fee, taxes etc. Rs. 860 per bus per annum Insurance Rs. 1,000 per bus per annum Repairs & Maintenance Rs. 3,500 per bus per annum Purchase price of bus (Life 12 years)

Rs. 1,50,000 each

Scrap value Rs. 30,000 Diesel cost Rs. 2.00 per litre.

Each bus gives an average mileage of 4 kms per litre of diesel. Seating capacity of each bus is 50 students. The seating capacity is fully occupied during the whole year. Students picked up and dropped within a range upto 4 kms. of distance from the school are charged half fare and fifty percent of the students travelling in each trip are in this category. Ignore interest. Since the charges are to be based on average cost, you are required to: (i) Prepare a statement showing the expenses of operating a single bus and the fleet of five

buses for a year. (ii) Work out the average cost per student per month in respect of (A) Students coming from a distance of upto 4 kms. from the school and (B) Students coming from a distance beyond 4 kms. from the school

Working Notes 1. Calculation of Diesel Cost per bus.

Number of trips of 8 kms. each day 8. Distance travelled per day by a bus: 8 × 8km / trip = 64 km. Distance travelled during a month : 64 × 25 = 1,600 km. Distance travelled p.a. 1,600 × 9 = 14,400 km. (May, June and December being vacation) Mileage 4 km./litre Diesel required 14,400/4 = 3,600 litres. Cost of diesel @ Rs. 2 per litre = Rs. 7,200 p.a. per bus.

2. Calculation of number of students per bus Bus capacity 50 students. Half fare 50% i.e. 25 students. Full fare 50% i.e. 25 students. Full fare students as equivalent to half fare students i.e. 50 students. Total number of half fare students. 75 students. per trip Total number of half fare students in two trips 150 students. On full fare basis, number of students in two trips 75 students.

Question 5 SHANKAR has been promised a contract to run a tourist car on a 20 km. long route for the chief executive of a multinational firm. He buys a car costing Rs. 1,50,000. The annual cost of insurance and taxes are Rs. 4,500 and Rs. 900 respectively. He has to pay Rs. 500 per month for a garage where he keeps the car when it is not in use. The annual repair costs are estimated at Rs. 4,000. The car is estimated to have a life of 10 years at the end of which the scrap value is likely to be Rs. 50,000.

Cost Accounting 9.6

He hires a driver who is to be paid Rs. 300 per month plus 10% of the takings as commission. Other incidental expenses are estimated at Rs. 200 per month. Petrol and oil will cost Rs. 100 per 100 kms. The car will make 4 round trips each day. Assuming that a profit of 15% on takings is desired and that the car will be on the road for 25 days on an average per month, what should he charge per round-trip? Answer

Statement of Operating cost. Standing charges Per Annum Per Month Rs. Rs. Depreciation Insurance Taxes Garage (Rs. 500 × 12) Annual repairs Driver's Salary (Rs. 300× 12) Incidental expenses (Rs. 200 × 12)

Total number of round trips per month : 25 days × 4 round trips per day = 100

Hence the charge per round trip = 100

22.822,8.Rs

= Rs. 88.22

* 20 kms. x 2 x 4 x round trips x 25 days = 4,000 kms. Question 6 The Union Transport Company has been given a twenty kilometer long route to play a bus. The bus costs the company Rs. 1,00,000. It has been insured at 3% per annum. The annual road tax amounts to Rs. 2,000. Garage rent is Rs. 400 per month. Annual repair is estimated to cost Rs. 2,360 and the bus is likely to last for five years. The salary of the driver and the conductor is Rs.600 and Rs. 200 per month respectively in addition to 10% of takings as commission to be shared equally by them. The manager's salary is Rs.1,400 per month and stationery will cost Rs. 100 per month. Petrol and oil cost Rs. 50 per 100 kilometers. The bus will make three round trips per day carrying on an average 40 passengers in each trip. Assuming 15% profit on takings and that the bus will ply on an average 25 days in a month, prepare operating cost statement on a full year basis and also calculate the bus fare to be charged from each passenger per kilometer.

Question 12 A truck starts with a load of 10 tonnes of goods from station P. It unloads 4 tonnes at station Q and rest of the goods at station R. It reaches back directly to station P after getting reloaded with 8 tonnes of goods at station R. The distances between P to Q, Q to R and then from R to P are 40 kms, 60 kms, and 80 kms, respectively. Compute 'Absolute tonne-km' and 'Commercial tonne-km'. (May, 1995, 4 marks)

Answer Absolute tonnes-kms = 10 tonnes × 40 kms + 6 tonnes × 60 kms. + 8 tonnes × 80 kms. = 1,400 tonnes – kms. Commercial tonnes-kms = Average load × Total kilometers travelled

= kms180tonnes3

)8610(

Cost Accounting 9.18

= 8 tonnes × 180 kms = 1,440 tonnes-kms Note: It may be noted that while calculating the absolute tonnes – kms, the travel between

any two stations is considered individually, while in the case of commercial tonne-kms, the trip is considered as a whole.

Question 13 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. Rs. 5,000 per month per drive. Cleaner's salary payable for all the 12 months Rs.3,000 per month per cleaner (one cleaner has been employed for every five buses).

Licence Fees, Taxes etc. Rs. 2,300 per bus per annum Insurance Premium Rs. 15,600 per bus per annum Repairs and Maintenance Rs. 16,400 per bus per annum Purchase price of the bus Rs. 16,50,000 each Life of the bus 16 years Scrap value Rs. 1,50,000 Diesel Cost Rs. 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:
