If an area's previous population was thirty lakh and its current population is thirty-six lakh, what is the growth percentage?

Answer and explanation

Correct answer: Twenty percent

The direct answer is B, twenty percent. First find the absolute increase: current population minus previous population equals 36 lakh minus 30 lakh, or 6 lakh. Then compare this increase with the previous population, because the growth percentage is calculated on the original base. The formula is: growth percentage = (increase ÷ previous population) × 100. Therefore, (6 ÷ 30) × 100 = 20%. Option A is wrong because 6 is not one-tenth of 30; it is one-fifth. Option C is wrong because 6 is not 30% of 30. Option D mistakes the current population figure for the growth percentage. Memory cue: subtract first, then divide by the old population, not the new population.
