Direction: Various expenditures incurred by a publishing company for publishing a book in 2011 are given below.
Study the chart and answer the questions.

1. Royalty of a book is less than the printing cost by

1. Required percentage

 = 20 - 15 × 100 = 25% 20

##### Correct Option: A

Required percentage

 = 20 - 15 × 100 = 25% 20

1. Price of a book is 20% above cost price. If the marked price is \$ 180, then the cost of paper for a single copy (in \$) is

1.  ∴ C.P. = 180 × 100 = \$ 150 120

 ∴ Cost per paper = 150 × 15 100

= \$ 22.50

##### Correct Option: C

 ∴ C.P. = 180 × 100 = \$ 150 120

 ∴ Cost per paper = 150 × 15 100

= \$ 22.50

Direction: The annual agricultural production (in tonnes) of an Indian State is given in the pie chart. The total production is 9000 tonnes. Read the pie chart and answer the question.

1. What is the annual production of wheat?

1. ∵ 360° ≡ 9000 tonnes

 ∴ 110° ≡ 9000 × 110 360

= 2750 tonnes

##### Correct Option: A

∵ 360° ≡ 9000 tonnes

 ∴ 110° ≡ 9000 × 110 360

= 2750 tonnes

1. The marks obtained in English, Physics and Social Science exceed the marks obtained in Mathematics and Chemistry by

1. English + Physics + Social Science = 200°
Maths + Chemistry = 160°
Required percentage

 = 40 × 100 = 100 % or 11 1 % 360 9 9

##### Correct Option: A

English + Physics + Social Science = 200°
Maths + Chemistry = 160°
Required percentage

 = 40 × 100 = 100 % or 11 1 % 360 9 9
