Question

9-the Average of 9 number is 14. One number 6 is excluded find the New average?

Answer 1

Answer:

15

Step-by-step explanation:

Average of 9 numbers is 14.

So, S₉/9 = 14 ==> S₉ = 14 * 9 = 126.

Now, 6 is excluded. So, S₈ = 126 - 6 = 120

So, New average = S₈/8 { 6 is excluded so, only 8 numbers are left.}

        New average = 120/8 = 15
