## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following pie chart carefully and answer the questions. The pie chart represents the percentage of people involved in various occupations. 1. The ratio of the people involved in service to that in industry is

1. As per the given pie chart in question ,
Percentage of people involved in industry = 30%
Percentage of people involved in service = 20% Required ratio = Percentage of people involved in service : Percentage of people involved in industry

##### Correct Option: B

As per the given pie chart in question ,
Percentage of people involved in industry = 30%
Percentage of people involved in service = 20% Required ratio = Percentage of people involved in service : Percentage of people involved in industry
Required ratio = 20 : 30 = 2 : 3

1. How many more people are involved in service than in trade?

1. On the basis of given pie chart in question ,
Total number of people = 20000
Percentage of people involved in trade = 6.7%
Percentage of people involved in service = 20%
Difference of percentage = (20 – 6.7)% = 13.3%
∴ Required answer = 13.3% of 20000

##### Correct Option: B

On the basis of given pie chart in question ,
Total number of people = 20000
Percentage of people involved in trade = 6.7%
Percentage of people involved in service = 20%
Difference of percentage = (20 – 6.7)% = 13.3%
∴ Required answer = 13.3% of 20000

 Required answer = 20000 × 13.3 = 2660 100

Direction: Study the pie chart given below and answer the following questions. 1. The ratio between royalty and binders’ charges is

1. As per the given pie chart in question ,
Percentage of royalty = 15%
Percentage of binders = 18%
Required ratio = Percentage of royalty : Percentage of binders

##### Correct Option: A

As per the given pie chart in question ,
Percentage of royalty = 15%
Percentage of binders = 18%
Required ratio = Percentage of royalty : Percentage of binders
Required ratio = 15 : 18 = 5 : 6

1. What should be the central angle of the sector ‘cost of paper’?

1. According to given pie chart in question ,
Percent of cost of paper = 10%
∵ 100% ≡ 360°

 ∴ 1% = 360° 100

##### Correct Option: C

According to given pie chart in question ,
Percent of cost of paper = 10%
∵ 100% ≡ 360°

 ∴ 1% = 360° 100

 We have , 10% ≡ 360 × 10 = 36° 100

1. The central angle of printing charge is x more than that of advertisement charges. Then the value of x is

1. As per the given pie chart in question ,
Percentage of printing charge = 35%
Difference of percentage charges on printing and advertisement = 35 – 18 = 17%
As we know that , 100% ≡ 360°

 ∴ 1% = 360° 100

##### Correct Option: B

As per the given pie chart in question ,
Percentage of printing charge = 35%
