1. If the total marks were 3000, then marks in Mathematics would be
1. 800
2. 750
3. 850
4. 900
Answer Option: 2
Marks obtained in Mathematics would be = 90 / 360 x 3000 = 750
2. The Marks scored in English and Mathematics is less than the marks scored in Science and Hindi by
1. 5%
2. 4.33%
3. 3.33%
4. 6%
Answer Option: 3
Marks scored in English and Mathematics = (55 + 90 ) / 360 x 900 = 362.5 Marks scored in Hindi and Science = (70 + 80) / 360 x 900 = 375 Percent decrease = 12.5 / 375 x 100 = 3.33
3. If the marks scored by the student are 137.5, then the subject is
1. English
2. Hindi
3. Mathematics
4. Science
Answer Option: 1
Going by the options, marks scored in English = 55 /360 x 900 = 137.5
4. Total marks scored in Social Science and English is
1. 400
2. 350
3. 500
4. 300
Answer Option: 4
Angle of English sector is 550 and angle of Social Science sector is 650.So sum of angles is 1200.Sum of marks =( 1200 x 900) / 360 = 300.
5. The difference of marks scored in Social Science and Science is
1. 37.5
2. 40
3. 20
4. 15
Answer Option: 1
Angle of Science sector is 800and angle of Social Science sector is 650. So difference of angle is 150 .Difference of marks = (150 x 900 ) / 3600 = 37.5
DIRECTIONS for questions 6 to 10: The following pie-diagram shows the expenditure incurred in the preparation of a book by a publisher, under various heads.
6. What is the difference between the angle of pie- diagram showing the expenditure incurred on binding and printing?
1. 24 deg
2. 48 deg
3. 18 deg
4. 15 deg
Answer Option: 3
Binding sector is 30% and Printing sector is 25%. So difference is 5%. Difference of angle = 5 x 360 / 1000 = 180
7. If the marked price of the book is Rs. 50,what is the cost of printing to publish a single copy of the book ,if the marked price of a book is 25% more than its cost price?
1. Rs.6
2. Rs.10
3. Rs.4.50
4. Rs.6.50
Answer Option: 2
The marked price = Rs.50/-. The cost price = 50 / 1.25 = 40
Cost of printing = 25% of 40 = 0.25×40= Rs 10.
8. By what percentage, expenditure on binding should be reduced so that its expenditure will be equal to paper expenditure?
1. 25%
2. 33.33%
3. 27 2/3%
4. 20%
Answer Option: 2
Binding expenditure = 30%, Paper expenditure = 20% Percent reduction = (30 - 20) /30 x 100 = 33.33%

9. If the sum of two expenditures is represented by 144 degrees in the diagram (if the diagram is made in terms of degrees), these expenditures are
1. Printing & Paper
2. Paper & Binding
3. Printing & Misc
4. Binding & Misc
Answer Option: 4
For printing and Paper = (25%+20%)=45%=1620
For paper and binding = (30%+20%)=50%=1800
For printing and misc = (25%+10%)=35%=1260.
For binding and misc = (30%+10%)=40%=1440.
10. Binding is more than printing charges by
1. 25%
2. 27 2/3%
3. 23.5%
4. 20%
Answer Option: 4
Binding is 30% of the total cost and printing is 25% of the total cost.
So, the required percentage = 30 - 25 / 25 x 100 = 5 / 25 x 100 = 20%
