Answer
0.48 (approx.)

The correct answer is 0.48 (approx.) — Thus the average annual increase is approximately 0.48 Diks per year.

Step-by-step solution

  1. Find the change in number of Diks: 18-6 = 12.
  2. Divide the change by the number of years: 12 ÷ 25 = 0.48.
  3. Thus the average annual increase is approximately 0.48 Diks per year.
Common mistake: Dividing by 24 instead of 25

Concept tested: Average annual change calculation
