Answer 2

Answer:

Mean of 9 numbers = 60.

Step-by-step explanation:

Question : The mean of 10 numbers is 58. If one of the number is 40, what is the mean of other nine ?

Given : The mean of 10 numbers = 58.

one of the number is 40.

To find : The mean of nine numbers.

Solution :

Mean : Mean is defined as the sum of all the observations divided by total number of observations.

Mean =     sum of observations          

           Total number of observations

since mean of 10 numbers =58 is given ,then

58 = sum of 10 numbers

                  10

58 × 10 = sum of 10 numbers

sum of 10 numbers = 580.

one of the number is 40, then sum of nine numbers =580 - 40 = 540.

Now, Mean of 9 numbers = sum of 9 numbers

                                                           9

       Mean of 9 numbers = 540 ÷ 9 = 60.
