2. 2 Exercise: A garments factory has 240 machine in operation manned by 220 operators. The machine cannot be worked without an operator wholly engaged on it. The original cost of all these 240 machines cost works out to Tk. 5000000. The following particulars are for a period of a year: Normal available hours per month---------------------------210 Absenteeism (without pay) hours per month-------------- 20 Leave (with pay) hours per month--------------------------- 20 Normal idle time (unavoidable ) hours per month--------10 Average rate of wages per day of 8 hours------------Tk 100 Production bonus estimated ---- 15% on wages Value of power consumed-------TK 100,000 Supervision & indirect labour --- TK. 200,000 Lighting and electricity-------------- TK 25,000 Repairs and maintenance including consumables 2% on value of machines Insurance ----------TK. 60,000 Depreciation 15% on original cost. Machine hour rate calculation

3. 3 Other sundry works expenses Tk. 50,000 General management expenses allocated Tk. 1,50,000 You are required to work out a comprehensive machine hour rate for the industry. Say monthly production is 60,000 pcs of shirt calculate cost of sales per DZ. Solution: Actual Factory overhead cost Machine Hour Rate = ------------------------------------- Actual Machine working hour Calculation: A) Effective hours of machine operations per operator per month = 210 – (20+20+10) = 160 hours. Therefore, the effective working hours for an operator is 160/month. Machine hour rate calculation

4. 4 Operators wages: Hours per month for which wages are payable = (220 – 20 ) @ 200 hours. Per hour wages = 100/8 = 12.5 TK. Computation of Comprehensive Machine hour Rate: Operator’s wages --------------(220x200x12.5x12)—66,00000 TK. Production bonus (15% of wages)------------------ 9,90,000 Power consumed ---------------------------------------- 1,00,000 Supervision and indirect labour----------------------- 2,00,000 Lighting and electricity ---------------------------------- 25,000 Repairs and maintenance (50,00000 @ 2%) 100,000 Insurance ----------------------------------------------- 60,000 Depreciation ------------------------------------------------ 750,000 Sundry Work Expenses------------------------------------ 50,000 General management expenses-------------------------- 150,000 ------------------- Total overheads of the factory TK. 90,25,000 Hours of machine operation 422400 hours Comprehensive machine hour rate = 21.36 TK
