Which option shows wrong understanding of growth rate and absolute increase?

Answer and explanation

Correct answer: Same percentage always gives the same absolute increase

Direct answer: A is the incorrect statement. Absolute increase means the actual number added or lost: final population minus initial population. Growth rate is usually expressed as a percentage and must be calculated using the initial population as the base. The same percentage does not always produce the same numerical increase. For instance, 5% of 200 is 10, whereas 5% of 2,000 is 100. Thus, A wrongly treats equal percentages as equal absolute changes. B is correct because absolute increase is the real numerical difference. C is correct because a percentage helps compare growth between populations of different sizes, although the base and period must be stated. D is correct because a larger base produces a larger absolute change at the same rate. Memory cue: rate is a percentage; increase is a number.
