20% is 30600.
Now what is 15%.
= 30600*15/20.
= 22950.
Now what is 15%.
= 30600*15/20.
= 22950.

@Ilya.
In the question it is mentioned that the publisher has to pay Rs. 30,600 as printing cost. The Pie chart shows the costing percentages for publishing the book.
1) Promotion cost is 10%.
2) Transportation cost is 10%.
3) Paper cost is 25%.
4) Binding cost is 20%.
5) Royalty is 15%.
6) Printing cost is 20%.
As per the question the publisher has to pay a printing cost of Rs. 30,600/- (where printing cost is 20% of book publishing cost).
Assume the publishing cost as X.
Then calculation is as below.
20% of X = 30600.
Then X = (30600*100)/20.
X = 153000 (i.e., Publishing cost).
Royalty cost is 15% of publishing cost 3.
Royalty cost = (15*153000) /100.
Royalty cost = 22950/-.

20% is equal to 30600.
15% = (30600*15/20) = 22950.
15% = (30600*15/20) = 22950.

20% = 30600.
10% = 30600/2 = 15300.
5% = 15300/2 = 7650.
We want 15% so 10%+5% = 15300+7650 = 22950.
10% = 30600/2 = 15300.
5% = 15300/2 = 7650.
We want 15% so 10%+5% = 15300+7650 = 22950.

30600 = 20%.
1% = 1530.
15% = 15 * 1530 = 22950.
1% = 1530.
15% = 15 * 1530 = 22950.

Why we get 20% in denominator?

In the first figure, 100 is up and 20 is below but in the second the figure 100 is down and 15 is up. How was that possible. Please explain in detail I am very weak in maths.

If given printing cost is 20% as in pie chart,
And royalty cost is 15%,
Then royalty is 3/4 of printing.
That gives 30600/4 = 7650.
So just that gives us royalty = 7650 * 3= 22950.
And royalty cost is 15%,
