1. Number of students who come to school by car.

 = 70 × 2160 = 420 360

Direction: Circle graph given below shows the expenditure incurred in bringing out a book by a publisher.
Study the graph and answer the question.

1. It the Miscellaneous charges is \$ 6,000, the Advertisement charges are :

1. ∵ 4% ≡ \$ 60000

 ∴ 18% ≡ \$ 6000 × 18 = \$ 27000 4

##### Correct Option: A

∵ 4% ≡ \$ 60000

 ∴ 18% ≡ \$ 6000 × 18 = \$ 27000 4

1. If the cost of printing is \$ 17,500, the Royalty is :

1. ∵ 35% ≡ \$ 17500

 ∴ 15% ≡ \$ 17500 × 15 = \$ 7500 35

##### Correct Option: C

∵ 35% ≡ \$ 17500

 ∴ 15% ≡ \$ 17500 × 15 = \$ 7500 35

1. If 5500 copies are published, Miscellaneous expenditures amount to \$ 1848 and publisher’s profit is 25%, then marked price of each copy is

1. ∵ 4% ≡ \$ 1848

 ∴ 100% ≡ \$ 1848 × 100 4

= \$ 46200
 ∴ C.P. of each book = 46200 5500

= \$ 8.4
∴ Marked price of each copy
 = 8.4 × 125 = \$ 10.50 100

##### Correct Option: B

∵ 4% ≡ \$ 1848

 ∴ 100% ≡ \$ 1848 × 100 4

= \$ 46200
 ∴ C.P. of each book = 46200 5500

= \$ 8.4
∴ Marked price of each copy
 = 8.4 × 125 = \$ 10.50 100

1. Royalty on the book is less than the Advertisement charges by :

1. Percentage decrease

 = 18 - 15 × 100 18

 = 50 = 16 2 % 3 3

##### Correct Option: D

Percentage decrease

 = 18 - 15 × 100 18

 = 50 = 16 2 % 3 3
