A country gains 300000 people through births and deaths but loses 100000 through migration. What is the actual population growth?

Answer and explanation

Correct answer: 200000

The correct answer is A: 200,000 people, or 2 lakh. The 300,000 gain from births and deaths is the natural increase. Migration causes a loss of 100,000, so its contribution is −100,000. Actual total population growth includes both effects: 300,000 + (−100,000) = 200,000. Option A correctly gives the net result. Option B reports only the natural increase and ignores migration. Option C adds the two magnitudes even though migration is a loss, so it uses the wrong sign. Option D reports only the migration loss and ignores births and deaths. The word “actual” is important because it asks for the final change after all components are combined. Memory cue: gains add, losses subtract; actual growth = natural increase + net migration.
