    Answer : Option A

    Explanation :

     = 30% of the total expenditure.

    From the pie chart it is clear that:

    Central angle of 108° = [ \(\frac { 108 } { 360}\) x 100] % of the total expenditure
    Binding Cost + Transportation Cost = (20% + 10%) of the total expenditure
      = 30% of the total expenditure.

    Therefore Binding Cost and Transportation Cost together have a central angle of 108°.
