Question #05e58

Answer 1

`x= 2.154 approx 2`

Explanation:

`7 : 78`
`x : 24`

For direct variation:

`x = 7 xx 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.
