## Introduction to Data Interpretation

#### Data Interpretation

Direction: The pie- chart, given here, shows various expenses of a publisher in the production and sale of a book. Study the chart and answer questions based on it.

1. The difference between the measure of central angles of sector for binding charges and advertisement charges is :

1. Central angle for binding charges

 = 360 × 18 = 64.8° 100

 = 360 × 18 = 64.8° 100

∴ Required difference = 0°
Method 2 :
Percentage value for both is same.
Therefore, difference between angles is same.

##### Correct Option: D

Central angle for binding charges

 = 360 × 18 = 64.8° 100

 = 360 × 18 = 64.8° 100

∴ Required difference = 0°
Method 2 :
Percentage value for both is same.
Therefore, difference between angles is same.

1. Miscellaneous expenses are what per cent of paper cost?

1. Required percentage

 = 4 × 100 = 40% 10

##### Correct Option: C

Required percentage

 = 4 × 100 = 40% 10

1. The measure of central angle for the section ‘printing cost’ is :

1. ∵ 100% ≡ 360°

 ∴ 35% ≡ 360 × 35 = 126° 100

##### Correct Option: A

∵ 100% ≡ 360°

 ∴ 35% ≡ 360 × 35 = 126° 100

1. If the printing cost is \$ 17,500, the ‘Royalty’ paid is :

1. ∵ 35% o 17500

 ∴ 15% ≡ 17500 × 15 = \$ 7500 35

##### Correct Option: B

∵ 35% o 17500

 ∴ 15% ≡ 17500 × 15 = \$ 7500 35

Direction: The pie- chart given here shows expenditures incurred by a family on various items and their savings, which amounts to \$ 8,000 in a month. Study the chart and answer the questions based on the pie-chart

1. How much more amount is spent on food than on housing?

1. Difference in degree of amount spent on food & housing = (120 – 105)

 = 15° 8000 × 15° = \$ 2000 60

##### Correct Option: C

Difference in degree of amount spent on food & housing = (120 – 105)

 = 15° 8000 × 15° = \$ 2000 60
