A country has a natural increase of 500000 but net migration of negative 700000. What will happen to the total population?

Answer and explanation

Correct answer: Decrease of 200000

The correct answer is D: a decrease of 200,000, or 2 lakh. Total population change combines natural increase and net migration. Write the values with their signs: 500,000 + (−700,000) = −200,000. The negative sign means that the population falls by 200,000. Option A has the correct magnitude but the wrong direction; the larger outflow of migrants makes the result negative. Option B incorrectly adds 500,000 and 700,000 as if both were increases. Option C treats only migration as the total change and ignores natural increase. Option D includes both components and gives the correct decrease. Memory cue: total change = natural increase + net migration; a negative net-migration value is subtracted.
