Let take A be the total amount and royalty be R.
Now we know 20%of A=30600 and 15%of A= R.
then w.r.t A,
20% x A = 30600 => A= 30600/20%.................................> (1)
15% x A = R => A= R/15%...............................................> (2)
So from Eq 1 and 2, w.r.t A,
we get,
30600/20%=R/15%.
so R=(30600 x 15%)/20%.
R=22950.
It is a shortcut method to do in the ratio for a pie chart.

20% = 30600.
15% = x.
20x = 30600 * 15.
X= 22950.
15% = x.
20x = 30600 * 15.
X= 22950.

Why we assume here 20%?
Raj said:

20 is not mentioned in the above question so how and why all of you using 20% = 30600?

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%,
Then royalty is 3/4 of printing.
That gives 30600/4 = 7650.
So just that gives us royalty = 7650 * 3= 22950.

Simply first calculate whole cost 30,600 = 20% of X.
X = 30,600/20 X 100 = 1,53000.
So ,
15% of 1,53,000 will be = 22,950.
X = 30,600/20 X 100 = 1,53000.
So ,
15% of 1,53,000 will be = 22,950.
