Rs. 20,000

Rs. 22,500

Rs. 25,500

Rs. 28,125

View answer & explanation

Correct answer is B

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

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
