If previous population is twenty lakh and current population is twenty five lakh, what is the increase?

Answer and explanation

Correct answer: Five lakh

Answer: A, five lakh. To find the absolute increase in population, subtract the previous population from the current population. Here, the current population is 25 lakh and the previous population is 20 lakh. Therefore, increase = 25 lakh − 20 lakh = 5 lakh. This is an absolute change, not a percentage or growth rate. Option A is correct because it gives the difference between the two populations. Option B is the old population, so it is not the increase. Option C is the present population, not the amount added. Option D results from adding 20 lakh and 25 lakh, but population increase is found by subtraction. Memory cue: current population minus previous population gives absolute increase.
