Calculate the machine hour rate from the following:

 

Rs

 Cost of machine  

18,000

 Cost of installation  

2,000

 Scrap value after 10 years  

2,000

 Rates and rent for a quarter for the shop  

600

 General lighting  

 200 p.m.  

 Shop supervisor‘s salary  

Rs.6,000 per quarter  

 Insurance premium for a machine  

 120 p.a.  

 Estimated repair  

 200 p.a.  

 Power 2 units per hour @ Rs.150 per 100 units  

 

 Estimated working hours p.a. 2,000  

 

The machine occupies 1/4th of the total area of the shop. The supervisor is expected to devote 1/6th of his time for supervising the machine. General lighting expenses are to be apportioned on the basis of floor area.
