On Sunday 845 people went to the zoo. On Monday only 169 people went. What is the percent decrease in the people visiting the zoo on Monday?

Correct option is D

​Given:

People on Sunday = 845

People on Monday = 169

Formula Used:
Percentage decrease = $$\frac{\text{Decrease in value}}{\text{Original value}} \times 100$$​​

Solution:

Percent decrease = $$\frac{845 - 169}{845} \times 100$$​​

​$$= \frac{676}{845} \times 100 =80\%$$​​
