## Introduction to Data Interpretation

#### Data Interpretation

Direction: The pie- chart shows Distribution of Special Children Population during the year 1994-96. Study the pie-chart and answer the following questions. 1. Find the approximate percentage distribution of children with auditory disorder.

1. According to given pie chart in question ,
Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
Number of children with auditory disorder = 871

 ∴ Required percent = Number of children with auditory disorder × 100 % Number of children with auditory disorder

##### Correct Option: C

According to given pie chart in question ,
Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
Number of children with auditory disorder = 871

 ∴ Required percent = Number of children with auditory disorder × 100 % Number of children with auditory disorder

 ∴ Required percent = 871 × 100 ≈ 41.7% 2085 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

1. What is the central angle corresponding to the sale of Hindi newspapers in locality E?

1. As per the given pie chart in question ,
Sales of Hindi News Papers in locality E = 4000
Total sales of Hindi News Papers = 3500 + 2400 + 3600 + 2500 + 4000 = 16000

 Required central angle = Sales of Hindi News Papers in locality E × 360° Total sales of Hindi News Papers

##### Correct Option: B

As per the given pie chart in question ,
Sales of Hindi News Papers in locality E = 4000
Total sales of Hindi News Papers = 3500 + 2400 + 3600 + 2500 + 4000 = 16000

 Required central angle = Sales of Hindi News Papers in locality E × 360° Total sales of Hindi News Papers

 Required central angle = 4000 × 360° = 90° 16000
