First calculate the TOTAL COST involved in all the process
20% of X = 30,600
so,
X=1,53,000
Now
15% of 1,53,000=22,950
20% of X = 30,600
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.

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.

20% = 30,600 ,
15%=30,600 * 15/20 = 22,950.
15%=30,600 * 15/20 = 22,950.

Royalty is 5% lesser than the Printing cost according to the pie chart.
20% of printing cost is 30,600.
Therefore,1% of the printing cost will be 30,600/20 =1530/-
1% of the printing cost is 1530/-
5% of will be 1530*5 = 7650/-
We know that Royalty is 5% lesser than Printing cost.
20% of printing cost - 5% = 15% of the Royalty
Therefore, 30,600 - 7650 = 22950.
So, it is Option C.
20% of printing cost is 30,600.
Therefore,1% of the printing cost will be 30,600/20 =1530/-
1% of the printing cost is 1530/-
5% of will be 1530*5 = 7650/-
We know that Royalty is 5% lesser than Printing cost.
20% of printing cost - 5% = 15% of the Royalty
Therefore, 30,600 - 7650 = 22950.
So, it is Option C.
