$x = 2.154 \approx 2$

#### Explanation:

$7 : 78$
$x : 24$

For direct variation:

$x = 7 \times \frac{24}{78} \approx 2.154$

Example : 7 apartments can accommodate 78 employees. How many apartments will be needed for accommodation of 24 employees?

Here we take $x$ as the number of apartments needed. As less number of employees are to be accommodated, less will be the number of apartments needed. So, this is direct variation.
