Question

5. The mean of 6 numbers is 24. If one number is excluded, the mean of the
remaining numbers becomes 22. Find the excluded number. please explain​

Answer 1

Step-by-step explanation:

Mean = Sum of observations / Number of observations

Given,

Mean of 6 numbers is 24

24 = Sum of observations/ 6

Sum of observations = 144

Now,

One number is excluded so mean is 22

22 = Sum of observations / 5

Sum of observations = 110

Excluded number = 144 - 110 = 24
