## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following is a horizontal bar diagram showing the accidents in which two-wheelers are involved with other objects. Study the diagram and answer the questions.

1. The difference in percentage between the accidents involving two-wheelers and two-wheelers and two-wheelers and other objects is respectively.

1. On the basis of given bar diagram in question ,we see that one box represents the number of 20.
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000
Number of accidents involving two-wheelers and two-wheelers = 230
Number of accidents involving two-wheelers and other objects = 770

 Percentage of accidents involving two-wheelers and two wheelers = 230 × 100 = 23% 1000

##### Correct Option: D

On the basis of given bar diagram in question ,we see that one box represents the number of 20.
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000
Number of accidents involving two-wheelers and two-wheelers = 230
Number of accidents involving two-wheelers and other objects = 770

 Percentage of accidents involving two-wheelers and two wheelers = 230 × 100 = 23% 1000

 Percentage of accidents involving two-wheelers and other objects = 770 × 100 = 77% 1000

∴ Required difference = Percentage of accidents involving two-wheelers and other objects - Percentage of accidents involving two-wheelers and two wheelers
Required difference = 77 – 23 = 54%

Direction: The following Pie Chart shows the export of different food grains from India in 2010. Study the chart and answer the questions :

1. If the revenue from 1 quintal of crop A is thrice that from 1 quintal of crop C, then the ratio of the total revenues of A and C is

1. As per the given above pie chart , we see
The corresponding angle of crop A = 72°
Total corresponding angle of crop C = 72°
The revenue from crop A = 1 quintal
The revenue from crop C = 1 quintal

##### Correct Option: D

As per the given above pie chart , we see
The corresponding angle of crop A = 72°
Total corresponding angle of crop C = 72°
The revenue from crop A = 1 quintal
The revenue from crop C = 1 quintal
From question ,
Required ratio = A : C = 3 × 72° : 1 × 36° = 6 : 1

1. If a total of 1.5 million quintals of crop F was exported, then the total quantity of D and E that was exported (in million quintals) was

1. On the basis of given pie chart in question ,
The corresponding angle of crop F = 45°
Total corresponding angle of food-grains = 360°
The corresponding angle of crop D and E = ( 18 + 18 )° = 36°
Total exported of crop F = 1.5 million quintals
∵ 45° = 1.5 million quintals

##### Correct Option: A

On the basis of given pie chart in question ,
The corresponding angle of crop F = 45°
Total corresponding angle of food-grains = 360°
The corresponding angle of crop D and E = ( 18 + 18 )° = 36°
Total exported of crop F = 1.5 million quintals
∵ 45° = 1.5 million quintals

 ∴ 36 ° = 1.5 × 36 = 1.2 million quintals 45

1. The three crops which combine to contribute to exactly 50% of the total export of food grains are

1. As per the given above question, we see in pie chart
Total corresponding angle of food-grains = 360°
The corresponding angle of crop ( A + B + C ) = 72° + 72° + 36° = 180° ,

##### Correct Option: C

As per the given above question, we see in pie chart
Total corresponding angle of food-grains = 360°
The corresponding angle of crop ( A + B + C ) = 72° + 72° + 36° = 180° ,
Which represents the 50% of the total export of food grains in given pie chart .So , correct answer is option C .

1. If a total of 1.5 million quintals of crop F was exported, the amount of total food grains exported (in million) quintals was

1. On the basis of given pie chart in question ,
Total export of crop F = 1.5 million quintals
The corresponding angle of crop F = 45°
Total corresponding angle of food-grains = 360°
∵ 45° = 1.5 million quintals

##### Correct Option: B

On the basis of given pie chart in question ,
Total export of crop F = 1.5 million quintals
The corresponding angle of crop F = 45°
Total corresponding angle of food-grains = 360°
∵ 45° = 1.5 million quintals

 ∴ 360 ° = 1.5 × 360 = 12 million quintals 45
