If the previous population was forty-five lakh and the increase was nine lakh, what was the growth percentage?

Answer and explanation

Correct answer: Twenty percent

The correct answer is B: twenty percent. Growth percentage tells us what fraction the increase represents of the previous population. Use the formula: growth percentage = (increase ÷ previous population) × 100. Here, the increase is 9 lakh and the previous population is 45 lakh. Therefore, (9 ÷ 45) × 100 = 0.2 × 100 = 20%. The lakh unit cancels because both values use the same unit. Option A is incorrect because 9 lakh is not one-tenth of 45 lakh. Option B is correct because 9 is one-fifth of 45, and one-fifth equals 20%. Option C would require an increase of 13.5 lakh. Option D would require 20.25 lakh. Memory cue: always use the earlier population as the base.
