Question

On Sunday, 845 people visited the zoo, whereas on Monday, only 169 people visited. Find the percentage decrease in the number of visitors on Monday.

• A. 20%
• B. 80%
• C. 30%
• D. 25%

Answer 1

The correct option is B 80%

Given : No. of visitors on Sunday = 845
No. of visitors on Monday = 169
Therefore, percentage decrease $=\frac{\text{decrease in quantity}}{\text{original quantity}}\times 100$

$=\frac{845-169}{845}\times 100$
$=\frac{676}{845}\times 100=80\%$
Hence, the percentage decrease in visitors on Monday is 80%
