Direction: Study the following bar diagram carefully and answer the four questions.
-
In which year for the company A the percentage increase of production of buses with respect to the previous year is maximum?
-
- 2010
- 2012
- 2011
- 2013
Correct Option: B
From the given bar diagram , we see
Production of buses by company A in 2009 = 64000
Production of buses by company A in 2010 = 70000
Increase in production = 70000 - 64000 = 6000
| Percentage increase ⇒ | × 100 | Production of buses by company A |
| Percentage increase in year 2010 ⇒ | × 100 ≈ 9.4 | 64000 |
Production of buses by company A in 2010 = 70000
Production of buses by company A in 2011 = 77000
Increase in production = 77000 - 70000 = 7000
| Percentage increase in year 2011 ⇒ | × 100 = 10 | 70000 |
Production of buses by company A in 2011 = 77000
Production of buses by company A in 2012 = 85000
Increase in production = 85000 - 77000 = 8000
| Percentage increase in year 2012 ⇒ | × 100 ≈ 10.4 | 77000 |
Production of buses by company A in 2012 = 85000
Production of buses by company A in 2013 = 93000
Increase in production = 93000 - 85000 = 8000
| Percentage increase in year 2013 ⇒ | × 100 ≈ 9.5 | 85000 |
Hence , correct answer is 2012 year .
