If the population of a certain city increased by 25% in 2 years, the new population was what percent of the old?

100%
110%
125%
150%

The correct answer is: 100%

When calculating percentages, it is important to remember that the base number is the original value or population. In this case, the old population is our base number. The new population, which has increased by 25%, can be translated to 100% + 25% = 125% of the old population. However, as we are calculating the new population as a percentage of the old population, we need to subtract the original 100% to get the increase. Therefore, the answer is 25%. The other options are incorrect interpretations of the given information. Option B (110%) would be the answer if the population had increased by 10%. Option C (125%) is the new population, not the percentage increase. Option D (150%) is not a percentage increase and is too high of a value to represent a population increase of 25%.
