Correct Option: C
According to given bar graph , we have
Population of the town in year 2005 = 6%
Population of the town in year 2006 = 3%
| Single equivalent percentage increase for 2005 and 2006 = |  | 6 + 3 + | 6 × 3 |  | % | |
| 100 |
Single equivalent percentage increase for 2005 and 2006 = 9.18%
Similarly,
| Single equivalent percentage increase for 9.18% and 4% = | | 9.18 + 4 + | 9.18 × 4 | | % | |
| 100 |
Single equivalent percentage increase for 9.18% and 4% = 13.18 + 0.3672 ≈ 13.55%
| Single equivalent percentage increase for 13.55% and 8% = | | 13.55 + 8 + | 13.55 × 8 | | % | |
| 100 |
Single equivalent percentage increase for 13.55% and 8% = 21.55 + 1.08 ≈ 22.63%
