#### Data Interpretation

Direction: Study the information given in each of these questions and then answer the questions.

1. What is the average female population in million?

1.  Average female population = sum of total numbers of females total number of cities

##### Correct Option: A

From above given table , we can see that
The total population of all cities = 12 + 15 + 17 + 19 + 22 = 85 million
Total males in all cities = 6.5 + 7.2 + 9.0 + 9.9 + 10.8 = 43.4 million
Total females = 85 – 43.4 = 41.6 million

 Average female population = sum of total numbers of females total number of cities

 = 41.6 = 8.32 million 5

Direction: Study the bar diagram and answer questions based on it.

1. In which year, maximum number of persons were killed in industrial accidents other than those killed in coal mines?

1. From the above given figure , we can see that
The maximum number of persons killed in industrial accidents are 1200 in 2006

##### Correct Option: A

From the above given figure , we can see that
The maximum number of persons killed in industrial accidents are 1200 in 2006
Hence the maximum number of persons were killed in industrial accidents = 1200 (in 2006)

1. In which year, minimum number of persons killed in industrial accidents and coal mines together?

1. From the above given figure , the minimum number of persons killed in industrial accidents and coal mines are ( 800 + 200 ) = 1000 in 2009

##### Correct Option: D

From the above given figure , the minimum number of persons killed in industrial accidents and coal mines are ( 800 + 200 ) = 1000 in 2009
Hence the minimum number of persons were killed = 1000 (In 2009)

1. The number of persons killed in coal mines in 2006 was what percent of those killed in industrial accidents in that year?

1.  Required percentage = The number of persons killed in coal mines in 2006 X 100% The number of persons killed in industrial accidents in 2006

##### Correct Option: B

As per given graph , we can see that
The number of persons killed in coal mines in 2006 = 300
The number of persons killed in industrial accidents in 2006 = 1200

 ∴ Required percentage = The number of persons killed in coal mines in 2006 X 100% The number of persons killed in industrial accidents in 2006

 ∴ Required percentage = 300 X 100% = 25% 1200
