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.

We are finding how much royalty is less than the printing cost. So as we have to know how much it is lesser than printing cost so that we have to divide it by printing cost.
@All.
I hope you got my point. Simple, understand with whom we are comparing with. That means in this question we are comparing with printing cost to know how much royalty is lesser than it. So divide with printing cost.

Royalty is 15% and printing cost is 20%.
Lets assume the cost price (C.P) of book is 100, then royalty = 15 , printing cost = 20.
This means that royalty is 75% of printing cost.
Thus the % difference between royalty and printing cost is (100% - 75%) = 25%.

A simple way of solution:
According to the question -
(20-15)% = 5%;
So here is the formula for less than - [Difference/ more * 100].
So here the difference is 20-15 = 5%.
More value is 20%;
so, according to the formula -
5/20*100
Ans = 25%.
According to the question -
(20-15)% = 5%;
So here is the formula for less than - [Difference/ more * 100].
So here the difference is 20-15 = 5%.
More value is 20%;
so, according to the formula -
5/20*100
Ans = 25%.

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.

Royalty = 15 % of C.P.
Printing = 20% of C.P.
The ratio between them = 15 : 20 = 3 : 4.
So , Royalty / Printing = 3/4 = 75%
If Royalty = 75% of the Printing cost.
then , The difference between them = 100% - 75% = 25%.
Printing = 20% of C.P.
The ratio between them = 15 : 20 = 3 : 4.
So , Royalty / Printing = 3/4 = 75%
If Royalty = 75% of the Printing cost.
then , The difference between them = 100% - 75% = 25%.

Sometimes percentage difference is only the difference between the percentage and in some case it is divided by something as done in this question.
How we judge which type of problem is this. ?
Please suggest me

Simply, let us consider the C.P of the book is Rs 100.
Now, Royalty on the book is Rs 5 less than Printing cost. so as to calculate the percentage decrease with printing price it is, 5/20 * 100 = 25% less.

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.

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.

Ans should be 5%.
Say price is 20,000.
So royalty:3000.
Printing comes out to be:4000.
And their difference is 1000 which is 5% of 20,000. So, the answer must be 5% rather than 25%.
