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

Royalty on the book is less than the printing cost by:

[A].

[B].

33	1	%
	5

[C].

20%

[D].

25%

Answer: Option E

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.

Therefore Percentage difference = Difference x 100 %

Printing Cost

= 5% of C.P. x 100 % = 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.

C.P means Cost Price

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.P100=5/20100=25% answer.

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

Neelam said: (Fri, Jan 20, 2012 12:13:35 PM)

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

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

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