If population increases from 96 lakh to 120 lakh, what is the percentage growth?

Answer and explanation

Correct answer: 25 percent

The correct answer is C: 25 percent. First find the absolute increase: 120 lakh − 96 lakh = 24 lakh. Percentage growth is calculated using the initial population as the base, not the final population. Therefore, percentage growth = (increase ÷ initial population) × 100 = (24 ÷ 96) × 100 = 25%. Option A is wrong because 20% would mean an increase of only 19.2 lakh over 96 lakh. Option B gives the increase in lakh, not the percentage. Option C correctly gives the percentage growth. Option D is too high; 30% of 96 lakh would be 28.8 lakh. Memory cue: percentage change always uses the original value as the denominator.
