If an area has 500 births and 300 deaths what will be natural increase?

Answer and explanation

Correct answer: 200

Direct answer: B, 200. Natural increase is calculated from births and deaths only; migration is not included. Write the figures in the formula: natural increase = number of births − number of deaths. Therefore, 500 − 300 = 200. The positive result means births are greater than deaths by 200, so the population has a natural increase of 200 people during the stated period. Option A is wrong because 100 does not result from the given subtraction. Option B is correct because it follows the formula exactly. Option C is wrong because 300 is the number of deaths, not the difference. Option D is wrong because adding births and deaths gives 800, but that is not natural increase. If rates are given instead of numbers, the same subtraction idea is used. Memory cue: births add, deaths subtract; do not add both.
