If a country's population increases by 36 percent over twelve years, which statement is definitely correct?

Answer and explanation

Correct answer: Final population is 136 percent of initial population

A total increase of 36 percent is measured relative to the initial population. Therefore, if the initial population is represented as 100 percent, the final population must be 100 percent plus 36 percent, or 136 percent of the initial population. This conclusion does not require knowing how the increase was distributed across the twelve years.

Hence option B is definitely correct. The data do not prove an exact annual rate of 3 percent; annual growth could vary, and compound growth would not equal a simple division in that way. They also do not reveal the birth rate or whether migration contributed. Only the final-to-initial relationship is certain.
