### Answers and Explanations

**Answer 1: d**Paper cost constitutes 10% of the total cost. The central angle of the whole circle is of 360

^{0}and it represent 100% cost. So paper cost = (360/100)x10 = 36

^{0}Hence, the correct answer is option d.

**Answer 2: b** The printing cost is 35% of the total cost and it is given that the printing cost is Rs 17500.
Hence, 35% of the total cost is Rs 17500.
=> Total cost = (17500/35) x 100 = Rs. 50000
Now, the royalty costs 15% of the total cost.
Hence, Royalty = Total cost = (15/100) x 50000 = Rs. 7500
Hence, the answer is option b.

**Answer 3: c** Miscellaneous expenses are 4% of the total cost and it is given that the miscellaneous expenses is Rs 6000.
Hence, 4% of the total cost is Rs 6000
=> Total cost = (6000/4)x100 = Rs. 150000
In terms of percentage, the binding and cutting charges are 3% more than royalty.
Hence, the difference between binding and cutting charges and royalty = (3/100)x 150000 = Rs. 4500
Hence, the correct answer is option c.

**Answer 4: b** In terms of percentage share, the Printing cost is 17% more than the Advertisement charges.The central angle of the whole circle is of 3600 and it represent 100% cost.
So, the required difference = (360/100) x 17 = 61.2^{0}0
Hence, the correct answer is option b.

**Answer 5: b** The data is given as a pie chart. So to calculate the required percentage, we do not need the actual amount spent as it will be cancelled out in the final calculations.
The paper cost is 10% and printing cost is 35% of the total cost.
Hence, the required percentage = (10/35)x 100 = 28.5%
Thus, the correct option is (b).
