In service costing, a 'composite cost unit' is best illustrated by which of the following?

Tonne-kilometre is a composite cost unit because it combines two measures, weight carried and distance travelled. Units like litre, unit of steel or machine hour use just one measure, so they are simple rather than composite units.

  2. BCost per litre of petrol
  3. CCost per unit of steel
  4. DCost per machine hour

Explanation

A composite unit combines two measures, such as tonnes and kilometres. Tonne-kilometre does this. The others are single-measure units.
