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

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)

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)

From the given above figure , the minimum number of persons killed in coal mines are 150 in 2007

Correct Option: B

From the given above figure , the minimum number of persons killed in coal mines are 150 in 2007
Hence the minimum number of persons were killed in coal mines = 150 (in 2007)

Correct Option: C

Total number of persons killed in industrial accidents and coal mines in
2006 = 1200 + 300 = 1500
2007 = 900 + 150 = 1050
2008 = 1100 + 200 = 1300
2009 = 800 + 200 = 1000
Total number of persons killed
= 1500 + 1050 + 1300 + 1000 = 4850
