III. The following piechart shows the percentage distribution of the expenditure incurred in publishing a book. Study the piechart and the answer the questions based on it.
Various Expenditures (in percentage) Incurred in Publishing a Book
1) If for a certain quantity of books, the publisher has to pay Rs. 30,600 as printing cost, then what will be amount of royalty to be paid for these books?
A. Rs. 19,450 B. Rs. 21,200
C. Rs. 22,950 D. Rs. 26,150
Answer: Option C
Explanation:
Let the amount of Royalty to be paid for these books be Rs. r
Then, 20:15 = 30600:r
r = Rs. 30600 x 15 = Rs. 22,950.
20
2) What is the central angle of the sector corresponding to the expenditure incurred on Royalty?
A. 15º B. 24º
C. 54º D. 48º
Answer: Option C
Explanation:
Central angle corresponding to Royalty = 15% of 360º
= 15 x 360º
100
= 54º.
3) The price of the book is marked 20% above the C.P. If the marked price of the book is Rs. 180, then what is the cost of the paper used in a single copy of the book?
A. Rs. 36 B. Rs. 37.50
C. Rs. 42 D. Rs. 44.25
Answer: Option B
Explanation:
Clearly, marked price of the book = 120% of C.P.
Also, cost of paper = 25% of C.P
Let the cost of paper for a single book be Rs. n.
Then, 120: 25 = 180: n
n = Rs. 25 x 180 = Rs. 37.50
120
4) If 5500 copies are published and the transportation cost on them amounts to Rs. 82500, then what should be the selling price of the book so that the publisher can earn a profit of 25%?
A. Rs. 187.50 B. Rs. 191.50
C. Rs. 175.00 D. Rs. 180.00
Answer: Option A
Explanation:
For the publisher to earn a profit of 25%, S.P. = 125% of C.P.
Also Transportation Cost = 10% of C.P.
Let the S.P. of 5500 books be Rs. x.
Then, 10 : 125 = 82500 : x
x = Rs. 125 x 82500 = Rs. 1031250.
10
S.P. of one book = Rs. 1031250 = Rs. 187.50
5500
5) Royalty on the book is less than the printing cost by:
A. 5.0% B. 33.5%
C. 20.0% D. 25.0%
Answer: Option D
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.
Percentage difference = Difference x 100%
Printing Cost
= 5% of C.P. x 100%
Printing Cost
= 25%.

Important Tips for DI preparation
Scan the Question: Most DI questions will consist of a bunch of statistics, numbers & diagrams that might look scary at first instance but are actually not at all difficult to solve. In fact the trend has been: the scarier a DI set/caselet looks, the easier it is to solve. So before you lose heart & move on to an easierlooking set/caselet, scan that scary set & the list of questions in it. There will be at least of couple of “sitters” (questions that can be easily answered).
Hone your Calculation Skills/Speed: The Date Interpretation section is calculationintensive. And by “calculations” we mean stuff like 556/874 and not 2*9=? Such calculations can eat up your time. It is imperative, therefore to get very, very comfortable with calculations. Learn shortcuts that will help you calculate in your head or better still; figure out how Vedic Math works. It will help you a lot.
Get familiar with all types of DI questions: When you have been practicing DI questions for a while, you will begin to notice that there are different types or formats of questions in this section. There will be bar charts, tables, pie charts etc. There will also be questions where a lot of text or information will be provided in a long paragraph. Work on your Reading & comprehension speed. It will go a long way in helping you tackle this section. Also try reading business newspapers which have articles that are dataintensive & have graphs & piecharts etc. After reading the article, try to mentally collate & analyze the data provided in them. Such activities will help you get into the “DI mode” & stay in that mode always.
Practice, practice, practice: The last but the most important piece of advice. Copious amount of practice will help you in two ways:
 Your speed will increase considerably. You would have attempted all kinds of DI questions many number of times. You will end up attempting more questions correctly, thus increasing your score
 Your confidence will increase considerably. You know you have practiced a lot! This will help you face tough questions with determination.
So try to solve at least three DI question every day. Refer to good books that have a lot of solved and unsolved questions for practice. Suggestions for good books have been provided in the introductory article.
