Dont look below without Solving its for u only :)

1. C
Let the amount of Royalty to be paid for these books be Rs. r.
Then, 20 : 15 = 30600 : r

 => r = Rs. (30600x15)/20
=> Rs. 22,950.

2. C
Central angle corresponding to Royalty = (15% of 360)º
= (15/100)x360º
= 54º.

3.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. (25x180)/120
= Rs. 37.50 .

4. 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.(125x82500)/10= Rs. 1031250.
Therefore S.P. of one book = Rs. 1031250/5500= Rs. 187.50 .

5. D

6. D
Central angle of 18º = (18/360)x100% 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.

7. 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. (105x281250)/15= Rs. 1968750.
Therefore S.P. of one book = Rs. 1968750/12500
= Rs. 157.50 .

8. B
Let the Promotion Cost for this edition be Rs. p.
Then, 25 : 10 = 56250 : p => p = Rs. (56250x10)/25
= Rs. 22,500.

9. A
Central angle of 108º = (108/360)x100% of the total expenditure
= 30% of the total expenditure.
From the pie chart it is clear that:
Binding Cost + Transportation Cost = (20% + 10%) of the total expenditure
= 30% of the total expenditure.
Therefore Binding Cost and Transportation Cost together have a central angle of 108º.
