   • ₹ 19.450
   • ₹ 21.200
   • ₹ 21,950
   • ₹ 22,950

Answer
Let the amount of Royalty to be paid for these books be ₹ r
Then. 20 : 15 = 30.600 : r
r = ₹ 30600 *15/20= ₹ 22,950.
So, Option D

2. What is the central angle of the sector corresponding to the expenditure incurred on Royalty?
   • 15°
   • 24°
   • 54°
   • 48°

Answer
Central angle corresponding to Royalty
= 15% of 360°
= 15/100 × 360°= 54°
So, Option C

3. The price of the book is marked 20% above the C.P. If the marked price of the book is ₹ 180, then what is the cost of the paper used in a single copy of the book?
   • ₹ 36
   • ₹ 37.50
   • ₹ 42
   • ₹ 44.25

Answer
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 ₹ n.
Then. 120 : 25 = 180 : n
n = ₹ (25 * 180/120) = ₹ 37.50
So, Option B

4. If 5500 copies are published and the transportation cost on them amounts to ₹ 82.500 then what should be the selling price of the book so that the publisher can earn a profit of 25%?
   • ₹ 187.50
   • ₹ 191.50
   • ₹ 175.00
   • ₹ 180.00

Answer
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 ₹ x.
Then, 10 : 125 = 82500 : x
x = ₹(125 * 82500/10) = ₹ 10,31,250.
S.P. of one book
= ₹ (1031250/5500)= ₹ 187.50
So, Option A

5. Royalty on the book is less than the printing cost by :
   • 5%
   • 33.5%
   • 20%
   • 25%

Answer
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 cost * 100%
= 5/20 * 100% = 25%
So, Option D.
