The number of learners at a school changed from 60 to 45. What is the percentage decrease?
Answer and explanation
Correct answer: D. 25%
- Step 1: The change is 15 learners.
- Step 2: Percentage change = change ÷ original × 100 = 15 ÷ 60 × 100 = 25%.
Answer
25%.
Why not the others: 15%: the actual difference was used as the percentage. 33,3%: the change was divided by the new value instead of the original value. 14,3%: the change was divided by the sum of both values.
