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

Answer and explanation

Correct answer: Thirty percent

The correct answer is B: thirty percent. First find the absolute increase: current population − previous population = 65 lakh − 50 lakh = 15 lakh. Next compare this increase with the previous population, because percentage growth is calculated from the starting value: (15 ÷ 50) × 100 = 0.3 × 100 = 30%. Option B is therefore correct. Option A, 20%, does not result from the required calculation. Option C, 50%, incorrectly treats the increase as equal to the entire base population. Option D, 15%, mistakes the increase of 15 lakh for a percentage. Memory cue: growth percentage = (increase ÷ original population) × 100, not increase divided by the new population.
