If population changes from 35 lakh to 32 lakh, what kind of change is it?

Answer and explanation

Correct answer: Decrease of 3 lakh

The direct answer is B: the population has decreased by 3 lakh. Compare the final value with the initial value. The population begins at 35 lakh and ends at 32 lakh, so the final value is smaller. The amount of decrease is 35 lakh − 32 lakh = 3 lakh. Option B is correct because it gives both the correct direction, decrease, and the correct amount, 3 lakh. Option A is wrong because it calls the change an increase even though the final value is lower. Option C is wrong because 32 lakh is the final population, not the change. Option D is wrong because 67 lakh is the sum of the two values, not the difference. A percentage decrease could be calculated separately, but it is not needed here. Memory cue: if final is smaller, subtract final from initial and write “decrease.”
