## Introduction to Data Interpretation

#### Data Interpretation

Direction: The follow- ing pie-diagram shows the expenditure incurred on the preparation of a book by a publisher, under different heads. Study the pie-diagram and answer the following questions. 1. The number of heads on which the expenditure on a book is more than the average is

1. Average expenditure percentage = 20%
Expenditure on Printing + Binding is more than average expenditure.

##### Correct Option: B

Average expenditure percentage = 20%
Expenditure on Printing + Binding is more than average expenditure.

1. Which two expenditures together will form an angle of 108° at the centre of the pie-diagram?

1. ∵ 360% ≡ 100%

 ∴ 108° ≡ 100 × 108 = 30% 360

i.e. Paper + Miscellaneous (A + D)

##### Correct Option: A

∵ 360% ≡ 100%

 ∴ 108° ≡ 100 × 108 = 30% 360

i.e. Paper + Miscellaneous (A + D)

1. If cost of publishing a book is \$ 200, then printing cost is (in \$)

1. ∵ 100% ≡ \$ 200

 ∴ 25% ≡ 200 × 25 = \$ 50 100

##### Correct Option: D

∵ 100% ≡ \$ 200

 ∴ 25% ≡ 200 × 25 = \$ 50 100

1. If the expenditure on printing and binding of one book is \$ 110, then the cost of production of the book is (in \$)

1. ∵ 55 % &equive; \$ 360°

 ∴ 100% ≡ 100 × 100 = \$ 200 55

##### Correct Option: B

∵ 55 % &equive; \$ 360°

 ∴ 100% ≡ 100 × 100 = \$ 200 55

1. Angle of the pie-chart representing expenditure incurred on paying royalty is

1. ∵ 100% ≡ 360°

 ∴ 15% ≡ 360 × 15 = 54° 100

##### Correct Option: D

∵ 100% ≡ 360°

 ∴ 15% ≡ 360 × 15 = 54° 100
