In a year, on an average, how many persons were killed in industrial accidents and coal mines together?
-
- 121.25
- 1212
- 1212.5
- 1000
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
| ∴ average = | sum of the total number of persons killed in industrial accidents and coal mines | |
| total number of years |
| = | 4850 | = 1212.5 |
