Hi
Here is your answer.
We know that mean of observations is equal to sum of observations divided by number of observation
Therefore,
We get
5x plus 20 divided by 5 is equal to 24
5x plus 20 is equal to 120
5x is equal to 100
and, x is equal to 20
Therefore,value of x is equal to 20
Hope it will help you my friend.........
