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

38% of Total population of village X = 12160∴ y × 38 = 12160 100 ⇒ y = 12160 × 100 = 32000 38
∵ 16% ≡ $ 32000∴ 11% ≡ 32000 × 11 = 22000 16

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

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

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 2009Population 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 2009Population of village V in 2010 = 20000 × 110 = 22000 100
∴ Population below poverty line = 58% of 22000∴ Population below poverty line = 22000 × 58 = 12760 100

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
