Answer:
Hence the correct option is option c. DMC over-allocated the overhead costs to the standard engines.
Explanation:
DMC over-allocated the overhead costs to the quality engines
All overheads have now been allocated within the ratio of machine-hours used i.e. 4:1
If however, ABC system were used, overheads associated with found out would are allocated within the ratio of batches i.e. 1:1
And hence, more overheads would are allocated to custom engines and fewer to plain engines.
The amount purchased overheads will remain equivalent. The systems are only used for the allocation of overheads.
