Directions to Solve
The following pie-chart shows the percentage distribution of the expenditure incurred in publishing a book. Study the pie-chart and the answer the questions based on it.
Various Expenditures (in percentage) Incurred in Publishing a Book
5.
Royalty on the book is less than the printing cost by:
Answer: Option
Explanation:
Printing Cost of book = 20% of C.P.
Royalty on book = 15% of C.P.
Difference = (20% of C.P.) - (15% of C.P) = 5% of C.P.

If question asked how much less than formula,
= (diff/big number)*100.
(5/20)*100 = 25%.
If how much more is asked then =(diff/small no)*100.
(5/15)*100= 100/3.
= (diff/big number)*100.
(5/20)*100 = 25%.
If how much more is asked then =(diff/small no)*100.
(5/15)*100= 100/3.

How can we know that we have to solve this with respect to printing price?

Royalty= 15. Printing Cost= 20.
(20-15)*100/20=25 or (15-20)*100/20=25.
Here we used divided by 20 just bcoz to get "LESS" value
{always divide by bigger value i.e., 20(>15)}
We used 100 to get %value.
(20-15)*100/20=25 or (15-20)*100/20=25.

Ya there is formula for difference as (Diff/Initial value) *100.

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

15*100/20=75% that means 15 is 25% less than 20.

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

Yes. Rishant is correct. It should have been divided by the royalty.

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

Here for better understanding,
Lets we can assume C.P.=100rs
now, 5% of C.P. is 5rs
and printing cost is 20% of C.P.=20rs
Now you can calculate:
% diff=5% of C.P./20% of C.P*100=5/20*100=25% answer.
