@All.
Understand this way,
Printing cost - 30600, which is 20% cost.
So, 1st find out what is the value of One % (1%). 30600/20=1530.
15% Royalty = 15*1530 = 22950.

20% = 30600,
1% = 1530,
15% = 1350*5,
= 22950.
1% = 1530,
15% = 1350*5,
= 22950.

Given that, the amount to be paid for printing books is 20% (Rs. 30,600).
This is 5 times lesser than the Total amount.
(i.e.) Total amount is = (30,600 x 5),
= 153,000.
We need to find that the amount to be paid by the publisher for the Royalty is 15% of the entire amount.
The amount paid for Royalty is 15%.
= (153,000 x 15 / 100) (i.e.) cut two zeroes on both.
= (1530 x 15),
= 22,950.

Suppose total expenses is X.
Total Printing cost is 20% of X.
i.e X*20/100.
As per question, it is Rs.30600.
i.e X * 20/100 = 30600
so, X is 153000
Here we have to calculate royalty which is 15% of X.
i.e 15%*153000 = 22950.

The percentage for royalty is 15%
The percentage of printing is 25% = 30,600.
30,600 X 15 divided by 25 = 22,950.
The percentage of printing is 25% = 30,600.
30,600 X 15 divided by 25 = 22,950.

Yes, I agree because the printing % is 20 and royalty % is 15.
So 20:15 =30600:X.
So 20:15 =30600:X.

20% of X = 30,600.
so,
X = 1,53,000.
Now;
15% of 1,53,000 = 22,950.
so,
X = 1,53,000.
Now;
15% of 1,53,000 = 22,950.

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.
