Rs. 20,000

Rs. 22,500

Rs. 25,500

Rs. 28,125

View answer & explanation

Correct answer is B

Let the Promotion Cost for this edition be Rs. p.

Then, 25 : 10 = 56250 : p => p = Rs. ( (56250 x 10)/25 ) = Rs. 22,500

For an edition of 12,500 copies, the amount of Royalty paid by the publisher is Rs. 281,250. What should be the selling price of the book if the publisher desires a profit of 5%?

Rs. 152.50

Rs. 157.50

Rs. 162.50

Rs. 167.50

View answer & explanation

Correct answer is 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. ( (105 x 281250)/15 ) = Rs. 1968750

Therefore S.P. of one book = Rs. ( 1968750/12500 ) = Rs. 157.50

Binding Cost and Promotion Cost

Paper Cost and Royalty

Binding Cost and Printing Cost

Paper Cost and Printing Cost

View answer & explanation

Central angle of 18° = ( 18/360 x 100 ) % 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.

Royalty on the book is less than the printing cost by:

10%

20%

25%

View answer & explanation

Correct answer is 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.

Therefore Percentage difference = ( Difference/Printing Cost x 100 ) %

= ( (5% of C.P.)/Printing Cost x 100 ) % = 25%

If 5500 copies are published and the transportation cost on them amounts to Rs. 82500, then what should be the selling price of the book so that the publisher can earn a profit of 25%?

Rs. 187.50

Rs. 191.50

Rs. 175

Rs. 180

View answer & explanation

Correct answer is 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)/10 ) = Rs. 1031250

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

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. ( (25 x 180)/120 ) = Rs. 37.50
