## Introduction to Data Interpretation

#### Data Interpretation 1. What is the difference between the total sale of English newspapers and the total sale of Hindi newspapers in all the localities together.?

1. On the basis of given pie chart in question ,
Sale of Hindi newspapers in the locality A = 3500 ;
Sale of Hindi newspapers in the locality B = 2400 ;
Sale of Hindi newspapers in the locality C = 3600 ;
Sale of Hindi newspapers in the locality D = 2500 ;
Sale of Hindi newspapers in the locality E = 4000
∴ Total sales of Hindi News Papers = 3500 + 2400 + 3600 + 2500 + 4000 = 16000
And Sale of English newspapers in the locality A = 2500 ;

##### Correct Option: C

On the basis of given pie chart in question ,
Sale of Hindi newspapers in the locality A = 3500 ;
Sale of Hindi newspapers in the locality B = 2400 ;
Sale of Hindi newspapers in the locality C = 3600 ;
Sale of Hindi newspapers in the locality D = 2500 ;
Sale of Hindi newspapers in the locality E = 4000
∴ Total sales of Hindi News Papers = 3500 + 2400 + 3600 + 2500 + 4000 = 16000
And Sale of English newspapers in the locality A = 2500 ;
Sale of English newspapers in the locality B = 2000 ;
Sale of English newspapers in the locality C = 1800 ;
Sale of English newspapers in the locality D = 3000 ;
Sale of English newspapers in the locality E = 200
∴ Total sales of English News Papers = 2500 + 2000 + 1800 + 3000 + 200 = 9500
Required difference = 16000 – 9500 = 6500

Direction: The following pie chart shows proportion of population of seven villages in 2009. Study the pie chart and answer the questions that follow : 1. In 2010, the population of ‘Y’ and ‘V’ increases by 10% each and the percentage of population below poverty line remains unchanged for all the villages. If in 2009, the population of village Y was 30,000, then the below poverty line population of village ‘V’ in 2010 is ______

1. As per the given pie chart in question ,
Population percentage of village V in 2009 = 10%
Population percentage of village Y = 15%
Population percentage of below poverty line of village V = 58%
The population of village Y = 30,000
∵ 15% ≡ 30000

 ∴ 10% ≡ 30000 × 10 = 20000 15

Population percentage of village V in 2009 = 20000
Now , Population of village V in 2010 = 110% of Population percentage of village V in 2009
 Population of village V in 2010 = 20000 × 110 = 22000 100

##### Correct Option: B

As per the given pie chart in question ,
Population percentage of village V in 2009 = 10%
Population percentage of village Y = 15%
Population percentage of below poverty line of village V = 58%
The population of village Y = 30,000
∵ 15% ≡ 30000

 ∴ 10% ≡ 30000 × 10 = 20000 15

Population percentage of village V in 2009 = 20000
Now , Population of village V in 2010 = 110% of Population percentage of village V in 2009
 Population of village V in 2010 = 20000 × 110 = 22000 100

∴ Population below poverty line = 58% of 22000
 ∴ Population below poverty line = 22000 × 58 = 12760 100

1. If the population of the village ‘R’ is 32000, then the below poverty line population of village ‘Y’ is

1. Here , The population of the village ‘R’ = 32000,
According to given pie chart in question ,
Population percentage of village R = 16%
Population percentage of village Y = 15%
∵ 16% ≡ 32000

 ∴ 15% ≡ 32000 × 15 = 30000 16

##### Correct Option: B

Here , The population of the village ‘R’ = 32000,
According to given pie chart in question ,
Population percentage of village R = 16%
Population percentage of village Y = 15%
∵ 16% ≡ 32000

 ∴ 15% ≡ 32000 × 15 = 30000 16

∴ Population below poverty line in village Y = 52% of 30000
 Population below poverty line in village Y = 30000 × 52 = 15600 100

1. The ratio of the below poverty line population of village ‘T’ to that of the below poverty line population of village ‘Z’ is

1. On the basis of given pie chart in question ,
Percent of the below poverty line population of village ‘T’ = 46%
Percent of population of village ‘T’ = 21%
Percent of the below poverty line population of village ‘Z’ = 42%
Percent of population of village ‘Z’ = 11%
Required ratio = ( Percent of the below poverty line population of village ‘T’ ) × ( Percent of population of village ‘T' ) : ( Percent of the below poverty line population of village ‘Z’ ) × ( Percent of population of village ‘Z' )

##### Correct Option: C

On the basis of given pie chart in question ,
Percent of the below poverty line population of village ‘T’ = 46%
Percent of population of village ‘T’ = 21%
Percent of the below poverty line population of village ‘Z’ = 42%
Percent of population of village ‘Z’ = 11%
Required ratio = ( Percent of the below poverty line population of village ‘T’ ) × ( Percent of population of village ‘T' ) : ( Percent of the below poverty line population of village ‘Z’ ) × ( Percent of population of village ‘Z' )
Required ratio = 46 × 21 : 42 × 11 = 23 : 11

1. If the below poverty line population of the village ‘X’ is 12160, then the population of village ‘S’ is

1. As per the given pie chart in question ,
Below poverty line population of the village ‘X’ = 12160
Percent of Below poverty line population of the village ‘X’ = 38%
Let Total population of village X = y
Percent of population of the village ‘X' = 16%
Percent of the population of village ‘S' = 11%
38% of Total population of village X = 12160

 ∴ y × 38 = 12160 100

 ⇒ y = 12160 × 100 = 32000 38

##### Correct Option: C

As per the given pie chart in question ,
Below poverty line population of the village ‘X’ = 12160
Percent of Below poverty line population of the village ‘X’ = 38%
Let Total population of village X = y
Percent of population of the village ‘X' = 16%
Percent of the population of village ‘S' = 11%
38% of Total population of village X = 12160

 ∴ y × 38 = 12160 100

 ⇒ y = 12160 × 100 = 32000 38

∵ 16% ≡ \$ 32000
 ∴ 11% ≡ 32000 × 11 = 22000 16
