Show answer & explanation

Correct answer: A

Concept

To convert a percentage distribution into a count, multiply the total by the percentage as a fraction: count = total × percentage/100.

When comparing two periods, calculate each period's count from its own total before taking the absolute difference.

Application

  1. Model C in 2021: 450,000 × 30/100 = 135,000.

  2. Model C in 2022: 520,000 × 25/100 = 130,000.

  3. The required difference is |135,000 − 130,000| = 5,000.

Cross-check

The 2022 total is larger, but its Model-C share is five percentage points lower. Direct calculation confirms that the two counts differ by 5,000.

Therefore, the required difference is 5,000.
