Assume the total number of books as 500,
15% of 500 = 75%,
20% of 500 = 100%,
Hence 100% - 75% = 25%.
Here 15% of 500 = 15/100 × 500 = 15 × 5 = 75.
15% of 500 = 75%,
20% of 500 = 100%,
Hence 100% - 75% = 25%.
Here 15% of 500 = 15/100 × 500 = 15 × 5 = 75.

Sometimes percentage difference is only the difference between the percentage and in some case it is divided by something as done in this question.

As the question was asked to find the %difference for royalty as of printing cost, we divide the difference with printing cost.

If there is no fixed amount then we can consider it as 100 or any amount.
I can't get in this case how is it 25%?

Divide by printing cost because they are comparing the cost of royality with respect to printing cost.

@Neelam.
If the question asked for how more % the printing cost was, it would be divided by royalty!

I am not able to understand why they have divided difference by printing cost not by royalty cost?

LET CP 100.
royalty 15.
printing cost 20,
difference/printing cost * 100,
= 5/20 * 100 ,
= 25%.

If A is x% of B then can we say A is (100-x) % less than B?
Can we generalize this fact?

Why do you have to find C.P and stuff you could just directly just do the damn chart.
