**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 / 100**

^{0}= 18^{0}**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%=162**

^{0}**For paper and binding = (30%+20%)=50%=180**

^{0}**For printing and misc = (25%+10%)=35%=126**

^{0}.**For binding and misc = (30%+10%)=40%=144**

^{0}.**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%**
