Answer and explanation
Correct answer: 10 percent
The actual increase in population is \(2200-2000=200\). Percentage growth is \(\frac{200}{2000}\times100=10\%\). Therefore, 10 percent is correct. Choosing 20 percent would use an incorrect base for comparison. Exam tip: always use the initial (old) population as the base when calculating percentage growth.
