If population increases from 4000 to 4800 what will be the percentage growth?
Answer and explanation
Correct answer: 20 percent
Increase in population = 4800 − 4000 = 800. Percentage growth is calculated using the initial population as the base: \(\frac{800}{4000}\times100=20\%\). Therefore, the correct answer is 20 percent. A growth of 25 percent of 4000 would be 1000, not 800. Exam tip: for percentage increase, always divide by the original value.
