Answer & Explanation

**Q1. Answer**: (**C**)

Let the amount of Royalty to be paid for these books be Rs. r.

Then, 20 : 15 = 30600 : r

ð r = Rs. 22,950

**Q2. Answer**: (**C**)

Central angle corresponding to Royalty = (15% of 360)º

[(15/100) *360]^{0}

= 54^{0}

**Q3. Answer: (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. 37. 50

**Q4. Answer**: (**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) x 10]= Rs. 1031250

S.P. of one book = Rs. (1031250/ 5500)= Rs. 187.50

**Q5. Answer**: (**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.

Percentage difference = [ (Difference/Printing) * 100%

= [ ( 5% of C.P./Printing Cost ) x 100%]

= 25%
