Answer 1

25 mice will be caught by cats in 100 seconds if 5 cats participate in this activity.​

Step-by-step explanation:

Given : 2 cats catch 2 mice in 20 seconds.

To find : How many mice will be caught by cats in 100 seconds if 5 cats participate in this activity ?

Solution :

Let the number of mice will be caught be 'x'.

2 cats catch 2 mice in 20 seconds.

5 cats catch x mice in 100 seconds.

Using time and work formula,

$\frac{2\times 20}{2}=\frac{100\times 5}{x}$

Taking x one side,

$x=\frac{100\times 5\times 2}{2\times 20}$

$x=5\times 5$

$x=25$

Therefore, 25 mice will be caught by cats in 100 seconds if 5 cats participate in this activity.​
