#### Data Interpretation

1. What is the ratio of the average number of sale of English newspapers in localities B and D together to the average sale of Hindi newspapers in all the localities?

1. On the basis of given pie chart in question ,
Sum of sale of English newspapers from the localities B and D = 2000 + 3000 = 5000
Sum of sale of Hindi newspapers in all five the localities = 3500 + 2400 + 3600 + 2500 + 4000 = 16000
Required ratio = Average of sale of English newspapers from the localities B and D : Average of sale of Hindi newspapers in all five the localities

##### Correct Option: A

On the basis of given pie chart in question ,
Sum of sale of English newspapers from the localities B and D = 2000 + 3000 = 5000
Sum of sale of Hindi newspapers in all five the localities = 3500 + 2400 + 3600 + 2500 + 4000 = 16000
Required ratio = Average of sale of English newspapers from the localities B and D : Average of sale of Hindi newspapers in all five the localities

 Required ratio = 5000 : 16000 2 5

Required ratio = 2500 : 3200 = 25 : 32

1. What is the ratio of average number of English newspapers from the localities B, C and E to the average number of Hindi newspapers from the localities A and D ?

1. As per the given pie chart in question ,
Sum of English newspapers from the localities B, C and E = 2000 + 1800 + 200 = 4000
Sum of Hindi newspapers from the localities A and D = 2500 + 3000 = 5500
Required ratio = Average of English newspapers from the localities B, C and E : Average of Hindi newspapers from the localities A and D

 Required ratio = (2000 + 1800 + 200) : (2500 + 3000) 3 2

##### Correct Option: C

As per the given pie chart in question ,
Sum of English newspapers from the localities B, C and E = 2000 + 1800 + 200 = 4000
Sum of Hindi newspapers from the localities A and D = 2500 + 3000 = 5500
Required ratio = Average of English newspapers from the localities B, C and E : Average of Hindi newspapers from the localities A and D

 Required ratio = (2000 + 1800 + 200) : (2500 + 3000) 3 2

 Required ratio = 4000 : 5500 3 2

 Required ratio = 8 : 11 = 16 : 33 3 2

1. What is the approximate sum of the ratios of sales of English and Hindi newspapers in all localities?

1. According to given pie chart in question ,
Total sales of English News Papers in all five localities = 2500 + 2000 + 1800 + 3000 + 200 = 9500
Total sales of Hindi News Papers in all five localities = 3500 + 2400 + 3600 + 2500 + 4000 = 16000
Ratio = Total sales of Hindi News Papers in all five localities : Total sales of English News Papers in all five localities

##### Correct Option: A

According to given pie chart in question ,
Total sales of English News Papers in all five localities = 2500 + 2000 + 1800 + 3000 + 200 = 9500
Total sales of Hindi News Papers in all five localities = 3500 + 2400 + 3600 + 2500 + 4000 = 16000
Ratio = Total sales of Hindi News Papers in all five localities : Total sales of English News Papers in all five localities
Ratio = 16000 : 9500 = 32 : 19
Required sum = 32 + 19 = 51

Direction: The following bar diagram shows the percentage of Hindus, Sikhs and Muslims in a state during the years from 2004 to 2007. Examine the bar diagram and answer the following questions.

1. If the total population of the state in 2004 was 5 lakhs, then the Hindu and Muslim population in that year was

1. From the given bar diagram , we see
Total population of the state in 2004 = 5 lakhs
Total percent of Hindu and Muslim population of the state in 2004 = 30 + 25 = 55%
Total ( Hindus + Muslims ) population in 2004 = 55% of 5 lakhs

##### Correct Option: B

From the given bar diagram , we see
Total population of the state in 2004 = 5 lakhs
Total percent of Hindu and Muslim population of the state in 2004 = 30 + 25 = 55%
Total ( Hindus + Muslims ) population in 2004 = 55% of 5 lakhs

 Hindus + Muslims = 500000 × 55 = 275000 100

1. The ratio between the Hindu and Sikh population in 2004 was

1. According to given bar graph , we have
The Hindu population in 2004 = 30%
And Sikh population in 2004 = 45%
Required ratio = The Hindu population in 2004 : Sikh population in 2004

##### Correct Option: C

According to given bar graph , we have
The Hindu population in 2004 = 30%
And Sikh population in 2004 = 45%
Required ratio = The Hindu population in 2004 : Sikh population in 2004
∴ Required ratio = 30 : 45 = 2 : 3
