Explanation:

The entire circle is of 360^o.
We need to find 108o is what percentage of 360^o, which looks like

108/360 x 100 = 30%
Now, let’s check among the options, the sum of the two entities must be 30%.
Binding Cost (20%) and Transportation Cost (10%), sum = 30%
Printing Cost (20%) and Paper Cost (25%), difference = 45%
Royalty (15%) and Promotion Cost (10%), difference = 25%
Binding Cost (20%) and Paper Cost (25%), difference = 45%

Hence, option 1 is the correct answer.
