EXERCISE 10.1

A 100 mild steel parts fabricated with RM 160 cost of materials and RM 200 cost of
direct labor. The overhead cost of the production is 35% of the total amount of
materials cost and direct labor cost. The fixed costs is 20% from overall cost. From

the information given, calculate:
a) overall cost;
b) if the management increased 10% of the total cost as a price per unit product,
calculate the overall costs.

Solution:

a) Overall cost = (Cost of Materials + Cost of direct labor + 35% of over head cost) +

20 % of (overall cost)
