2.On Sunday 845 people went to the Zoo. On Monday only 169 people went. What is the per cent decrease in the people visiting the Zoo on Monday?

Given, Number of people went to Zoo on Sunday = 845
Number of people went to Zoo on Monday = 169

So the decrease in number of people visiting the Zoo = 845 – 169 = 676

Hence we have the decrease in percent:

\(=\frac{decrease \;in \;the \;number \;of\; people\; visiting \;the \;zoo}{total \;number\; of \;people\; visiting \;the \;zoo \;on\; sunday}\times 100\)

\(= \frac{676\times100}{845}=80\)%

Hence we have the decrease in per cent of visiting people= 80%
