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
Rs. 20,000
Rs. 22,500
Rs. 25,500
Rs. 28,125
Correct answer is B
Let the Promotion Cost for this edition be Rs. p.
Then, 25 : 10 = 56250 : p => p = Rs. ( (56250 x 10)/25 ) = Rs. 22,500
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
Rs. 152.50
Rs. 157.50
Rs. 162.50
Rs. 167.50
Correct answer is B
Clearly, S.P. of the book = 105% of C.P.
Let the selling price of this edition (of 12500 books) be Rs. x.
Then, 15 : 105 = 281250 : x => x = Rs. ( (105 x 281250)/15 ) = Rs. 1968750
Therefore S.P. of one book = Rs. ( 1968750/12500 ) = Rs. 157.50
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
Binding Cost and Promotion Cost
Paper Cost and Royalty
Binding Cost and Printing Cost
Paper Cost and Printing Cost
Correct answer is D
Central angle of 18° = ( 18/360 x 100 ) % of the total expenditure
= 5% of the total expenditure.
From the given chart it is clear that:
Out of the given combinations, only in combination (d) the difference is 5% i.e.
Paper Cost - Printing Cost = (25% - 20%) of the total expenditure
= 5% of the total expenditure.

Royalty on the book is less than the printing cost by:
5%
10%
20%
25%
Correct answer is D
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/Printing Cost x 100 ) %
= ( (5% of C.P.)/Printing Cost x 100 ) % = 25%
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
Rs. 187.50
Rs. 191.50
Rs. 175
Rs. 180
Correct answer is A
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)/10 ) = Rs. 1031250
Therefore S.P. of one book = Rs. ( 1031250/5500 ) = Rs. 187.50
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
Rs. 36
Rs. 37.50
Rs. 42
Rs. 44.25
Correct answer is B
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)/120 ) = Rs. 37.50
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.

What is the central angle of the sector corresponding to the expenditure incurred on Royalty?
15°
24°
54°
48°
Correct answer is C
Central angle corresponding to Royalty = (15% of 360)° = ( 15/100 x 360 )° = 54°.
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
Rs. 19,450
Rs. 21,200
Rs. 22,950
Rs. 26,150
Correct answer is C
Let the amount of Royalty to be paid for these books be Rs. r.
Then, 20 : 15 = 30600 : r => r = Rs. ( (30600 x 15)/20 ) = Rs. 22,950
In a school the periodical examination are held every second month. In a session during April 2001 - March 2002, a student of Class IX appeared for each of the periodical exams. The aggregate marks obtained by him in each perodical exam are represented in the line-graph given below.
Marks Obtained by student in Six Periodical Held in Every Two Months During the Year in the Session 2001 - 2002.
Maximum Total Marks in each Periodical Exam = 500
None
June, 01
Oct, 01
Feb, 02
Correct answer is A
As is clear from the graph, the total marks obtained in periodical exams, go on increasing. Since, the maximum marks for all the periodical exams are the same; it implies that the percentage of marks also goes on increasing.
Thus, in none of the periodical exams, there is a fall in percentage of marks compared to the previous exam.

Correct answer is C
Average marks obtained in all the periodical exams
= 1/6 x [360 + 365 + 370 + 385 + 400 + 405] = 380.83 ≈ 381.
