Answer:
c) 60% of direct labour cost
Step-by-step explanation:
Indirect costs are also known as overheads. They are costs which are not incurred directly for the service been rendered. These costs can allocated to the cost of the core service using the direct labour cost basis as requested by the question.
To ascertain the indirect costs rate, we use the formula below:
Indirect cost rate = (Indirect cost/Direct labour cost) × 100
From the question,
Indirect cost = total cost less the direct labour cost
Indirect cost = $4,000,000 - 2,500,000
= $1,500,000
Indirect cost rate = Indirect cost/Direct labour cost × 100
= 1,500,000/2,500,000 × 100
= 60% of direct labour cost
