Question

The number of visitors in a national park on a public holiday was 600. On the next day, which was a working day, there were only 240 visitors. What was the percentage decrease in the number of visitors on the working day?

• A. 80%
• B. 20%
• C. 40%
• D. 60%

Answer 1

The correct option is D 60%

Given,
Number of visitors in the national park on a public holiday $=600$
Number of visitors in the national park on a working day $=240$
Percentage of change $=\frac{\text{Number of visitors in the national park on a working day-number of visitors in the national park on a public holiday}}{\text{Number of visitors in the national park on a public holiday}}\times 100\%$
$=\frac{240-600}{600}\times 100\%$
$=\frac{-360}{600}\times 100=-60\%$
The negative sign indicates that there is a decrease in the number of visitors.
Hence, the percentage decrease in the number of visitors on the working day is $60\%.$
