## Introduction to Data Interpretation

#### Data Interpretation

Direction: This is a pie-chart for the data on A, B, O, AB blood groups of 150 donors. Observe the pie-chart and answer the questions. 1. The number of persons having either blood group ‘A’ or blood group ‘B’ is :

1. As per the given pie chart in question ,
Total number of A, B, O and AB blood groups of donors = 150
The corresponding angle of blood group ‘B’ donors = 129.6°
The corresponding angle of blood group ‘A’ donors = 72°
The corresponding angle of all blood group donors = 360°

 Persons with blood group A or B = (129.6 + 72) × 150 360

##### Correct Option: A

As per the given pie chart in question ,
Total number of A, B, O and AB blood groups of donors = 150
The corresponding angle of blood group ‘B’ donors = 129.6°
The corresponding angle of blood group ‘A’ donors = 72°
The corresponding angle of all blood group donors = 360°

 Persons with blood group A or B = (129.6 + 72) × 150 360

 Persons with blood group A or B = 201.6 × 150 = 84 360

1. The number of donors having blood group ‘O’ is :

1. As per the given pie chart in question ,
Total number of A, B, O and AB blood groups of donors = 150
The corresponding angle of blood group ‘O’ donors = 100.8°
The corresponding angle of all blood group donors = 360°

 Number of blood group ‘O’ donors = The corresponding angle of blood group ‘O’ donors × Total number of all blood groups of donors The corresponding angle of all blood group donors

##### Correct Option: B

As per the given pie chart in question ,
Total number of A, B, O and AB blood groups of donors = 150
The corresponding angle of blood group ‘O’ donors = 100.8°
The corresponding angle of all blood group donors = 360°

 Number of blood group ‘O’ donors = The corresponding angle of blood group ‘O’ donors × Total number of all blood groups of donors The corresponding angle of all blood group donors

 Number of blood group ‘O’ donors = 100.8 × 150 = 42 360

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. What is the respective ratio between language disorder and the average of the remaining disorder cases?

1. According to given pie chart in question ,
Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
Number of children with language disorder = 657
Number of children with disorders except language disorder = Total number of children : Number of children with language disorder
Number of children with disorders except language disorder = 2085 – 657 = 1428

##### Correct Option: A

According to given pie chart in question ,
Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
Number of children with language disorder = 657
Number of children with disorders except language disorder = Total number of children : Number of children with language disorder
Number of children with disorders except language disorder = 2085 – 657 = 1428

 Their average = 1428 = 357 4

Required ratio = 657 : 357 = 219 : 119

1. Find the ratio between articulatory disorder and speech disorder cases.

1. On the basis of given pie chart in question ,
Total number of children with articulatory disorder = 60
and Total number of children with speech disorder = 275
Required ratio = Total number of children with articulatory disorder : Total number of children with speech disorder

##### Correct Option: D

On the basis of given pie chart in question ,
Total number of children with articulatory disorder = 60
and Total number of children with speech disorder = 275
Required ratio = Total number of children with articulatory disorder : Total number of children with speech disorder
Required ratio = 60 : 275 = 12 : 55

1. What is the average number of cases in different types of special children during the year 1994-96?

1. As per the given pie chart in question ,
Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
Total number types of special children = 5

 Required average = Total number of children Total number types of special children

##### Correct Option: A

As per the given pie chart in question ,
Total number of children = 871 + 222 + 275 + 657 + 60 = 2085
Total number types of special children = 5

 Required average = Total number of children Total number types of special children

 Required average = 2085 = 417 5
