Please any one can help me to solve this question: not sure of cost drivers for Utilities/Salaries of supervisor/salaries of cleaners/Misc cost:

RCL manufactures three products. Presently, overheads are allocated to each product on
the basis of direct labour hours. In order to determine the cost of products more accurately,
RCL has decided to implement Activity Based Costing for allocation of overheads.
The following data has been extracted from RCL’s budget for the next year:

Batch size units 500 250 250
Inspection time per batch hours 20 15 18
