If there are 200 births and 150 deaths, what will the natural increase be?

Answer and explanation

Correct answer: 50

Direct answer: A, 50. Natural increase means the change caused only by births and deaths, without considering migration. The formula is natural increase = births − deaths. Substituting the given values gives 200 − 150 = 50. Thus, births exceed deaths by 50, so the population has a natural increase of 50 people. A is correct. B is only the number of deaths, not the difference between births and deaths. C is only the number of births and ignores deaths. D is the sum of births and deaths; adding them does not show increase because deaths reduce population rather than add to it. A safe memory cue is “born minus gone by death.” If migration were also given, it would be considered separately for total population change, but it is not part of this natural-increase calculation.
